Here you go:
I found it in my Celebrations Italian Style cookbook, and since I don't have time to type it I decided to check out Mary's website.
Thank heavens she had it listed there, can you believe it?
I am sure every family puts their own touch to it, but at least this will give you a good basic recipe!
Hope he enjoys it.
Happy Easter, and hope your MIL is recovering well.

PIZZA CHENA
SERVES 10 TO 12
Pizza chena (its name is a Neapolitan dialect term meaning "full pie") was always a part of our Easter table when I was a child. This enormous two-crusted pie was stuffed with salami, prosciutto, cheeses of all sorts, bacon, and a dozen eggs! I have reduced the number of eggs, but this still remains a substantial and memorable dish.
DOUGH
1 tablespoon active dry yeast
2 1/2 cups warm (110º to 115ºF) water
5 1/2 to 6 cups unbleached all-purpose flour
1 teaspoon fine sea salt
2 1/2 teaspoons Colavita (tm) Extra Virgin Olive Oil
FILLING
3/4 pound fresh mozzarella cheese (fior di latte), thinly sliced
1/2 pound ham, thinly sliced
1/2 pound provolone cheese, thinly sliced
1/2 pound Genoa salami, thinly sliced
1/2 pound Swiss cheese, thinly sliced
1/2 pound capocollo, thinly sliced
6 large eggs
1/2 cup freshly grated Parmigiano-Reggiano cheese
1/3 cup minced flat-leafed parsley
Fine sea salt and freshly ground black pepper to taste
1 egg beaten with 1 teaspoon water; for egg wash
In a large bowl, sprinkle the yeast over 1 cup of the warm water, stir well, and let proof for 5 to 10 minutes, or until foamy. Add the remaining 1 1/2 cups water and stir well.
In another bowl, mix 5 cups of the flour with the salt. Add to the yeast mixture along with 1 teaspoon of the olive oil. Mix with your hands, adding additional flour if necessary, until a soft and no longer sticky dough is formed.
Turn the dough out onto a floured surface and knead it until smooth and elastic. Lightly grease a large bowl with olive oil, add the dough, and turn to coat. Cover tightly with plastic wrap and let rise in a warm place until doubled in bulk.
Preheat the oven to 375ºF. Brush the bottom and sides of a 15 × 13-inch baking dish or a 10 × 3-inch springform pan with the remaining 1 1/2 teaspoons olive oil. Punch down the dough and knead it on a floured surface for 3 or 4 minutes. Divide the dough in half. On a floured surface, roll one piece of the dough to a rectangle or round at least 2 inches larger than the pan. Fit the dough in the pan, stretching it up the sides so that it overhangs the rim.
Fill the pan with alternating layers of the sliced cheeses and meats (you should have at least 10 layers).
In a bowl, whisk together the eggs, Parmigiano-Reggiano cheese, parsley, and salt and pepper. Pour the mixture evenly over the cheese and meat.
Break a lemon-size piece of dough off the remaining piece of dough and set aside. On a floured surface, roll the second piece of dough out to a rectangle or round at least 1 inch larger than the pan. Place the dough over the filling and seal the edges by pinching them closed and rolling the seam underneath itself. Divide the reserved piece of dough in half and roll each piece into a rope. Lay one piece across the center of the pie, and lay the second piece across it to form a cross.
Brush the top of the pie evenly with the egg wash. Bake for 35 to 40 minutes or until the crust is nicely browned. Remove from the oven and let cool completely.
If using a springform pan, release the spring, transfer the pie to a serving plate, and cut into wedges. If using a rectangular pan, cut the pie into pieces in the pan, then transfer them to a serving dish.
Note: This pie will keep for up to 1 week in the refrigerator. It is best served at room temperature or just slightly warm.
