This is an article from Dallas Morning News that I've saved. It has 2 recipes, but then at the bottom has some suggestions for building your own Tex-Mex casseroles. I tried the Chicken Tortilla with Salsa Verde, and MMMMMMM (though I skipped the onions due to a persnickity husband). We especially like these as they don't include a bunch of preservative-filled sauces. It really, really makes a difference if you follow the directions and toast (or less healthy: fry) the corn tortillas first. Makes them less soggy.

Tortilla casseroles are more than just a way to use leftovers

CHICKEN TORTILLA CASSEROLE WITH SALSA VERDE
4 (7-ounce) cans of Herdez salsa verde (divided use, see note)
1 cup light sour cream
1 ½ cups canned chicken broth
16 tortillas
3 ½ to 4 cups shredded cooked chicken
½ white onion, grated
3 ½ cups Monterey Jack cheese, or any Mexican melting cheese
Sliced red onion, for garnish
In a large bowl, combine 21/2 cups of the salsa verde with sour cream and chicken broth. Set aside.
Preheat oven to 350 F. Spread tortillas out on 2 large baking sheets sprayed with nonstick cooking spray. Spray tortillas lightly with nonstick cooking spray, and bake for 10 minutes. Flip tortillas over, and bake for 3 more minutes.
Break tortillas into halves. Spread a thin layer of sauce on the bottom of a 9x13-inch baking dish. In a single layer, cover with 8 tortilla halves. Spread 1/3 of the chicken over the tortillas. Spread 1/3 of the grated onion over chicken. Cover evenly with about 11/2 cups of the sauce. Top with 1/3 of the cheese.
Repeat layers, ending with cheese. Cover tightly with foil, and bake for 30 minutes. Remove foil and bake until bubbly, 5 to 10 minutes longer. Let sit a few minutes before cutting.
Drizzle lightly with some of the remaining salsa verde (and reserve some to pass at the table). Garnish with sliced red onion. May be prepared a day ahead of time, for a firmer casserole. Makes 6 to 8 servings.
Note: Sold at Hispanic markets and some mainstream supermarkets.

TAMAL AZTECA
1 (28-ounce) can plum tomatoes, undrained (preferably Muir brand or other fire-roasted tomatoes)
1 chipotle chile in adobo sauce (canned), plus 2 to 2 ½ teaspoons of adobo sauce
½ tablespoon vegetable oil
1 cup white onion, finely chopped
2 garlic cloves, minced
1 ¼ cups canned chicken broth
Salt to taste
8 corn tortillas
1 cup zucchini cut in ¼ -inch dice
1 (16-ounce) package frozen chopped spinach, defrosted and squeezed dry
3 cups grated Monterey Jack, or any Mexican melting cheese (divided use)
1 cup frozen corn, thawed
Chopped cilantro, for garnish (optional)
Combine the tomatoes and chile in a blender and process to a coarse purée.
Heat the oil in a large skillet or Dutch oven over medium heat. Add onion and cook until lightly browned. Increase heat to medium-high, add garlic and cook 1 minute. Add tomato mixture and cook, stirring frequently, until reduced and thickened, about 8 minutes. Add broth; reduce heat to low and simmer, uncovered, stirring occasionally for 20 minutes. Stir in salt to taste, and remove from heat.
While sauce is cooking, preheat oven to 350 F. Spread tortillas out onto 2 baking sheets that have been sprayed with nonstick cooking spray. Lightly spray tortillas with nonstick cooking spray, then bake for 10 minutes. Turn tortillas over and bake for 3 more minutes. Remove, but leave oven set at 350 F.
Steam diced zucchini until tender, about 2 minutes (may be cooked in the microwave, covered with 2 tablespoons water).
Lightly coat a 9x9-inch baking dish with nonstick cooking spray. Spread a thin layer of sauce evenly over the bottom. Cover sauce with 2 toasted tortillas, broken into fourths. Evenly spread the chopped spinach over the top of the tortillas. Top with one-fourth of the remaining sauce and one-fourth of the cheese.
Distribute 2 more quartered tortillas over the top and press down. Spread the corn on top, and cover with 1/3 of the remaining sauce and cheese. Top with 2 more quartered tortillas, again pressing down. Top with zucchini, half of the remaining sauce and half of the remaining cheese.
Quarter the remaining 2 tortillas and distribute over the top, followed by remaining sauce and cheese. Cover with foil and bake 25 minutes. Uncover, and bake for an additional 10 minutes, until bubbling and lightly browned. Let stand a few minutes before cutting into squares. Garnish with chopped cilantro, if desired. Makes 4 servings.

DESIGN YOUR OWN TORTILLA CASSEROLE
Once you understand how to assemble the basic tortilla casserole, it's easy to create your own version using leftovers. Here are some guidelines.
BASIC AMOUNTS
For a 9x13-inch casserole, use 15 to 16 tortillas, 5 to 6 cups sauce (depending on thickness), 3 to 4 cups meat or vegetable filling and 3 to 4 cups cheese.
TOAST FIRST
Always toast the tortillas first, or your casserole will be mushy. (Some recipes call for frying in oil, but we found toasting to be easier and less greasy.)
To toast, preheat the oven to 350 F and spread the tortillas on baking sheets sprayed with nonstick cooking spray. Spray the tortillas lightly, then bake for about 10 minutes; turn and bake 3 minutes on the other side.
SUGGESTED FILLINGS
Cooked ground beef, leftover meats such as pulled pork or brisket, chorizo, black or pinto beans, shrimp, Swiss chard, mushrooms, canned green chiles. Feel free to combine ingredients for a more interesting casserole.
SUGGESTED CHEESES
Smoked mozzarella, queso Oaxaca, queso Chihuahua, cheddar mixed with Monterey Jack, pepper jack, mozzarella topped with goat cheese.
SUGGESTED SAUCES
Bottled or canned salsas lightened with chicken stock, cream or sour cream; canned enchilada sauce; Alfredo sauce spiked with green chiles or chipotle chiles.
SUGGESTED GARNISHES
Crumbled añejo cheese, sliced red onions, roasted poblano chiles, chopped cilantro.
PANS
Use a smaller pan for a thicker casserole; adjust baking time accordingly. For a pie, bake in a springform pan (as shown on the cover).
