I'm pretty sure I got this here - Chili Dog Cassserole
*a package of hot dog buns, cut up and placed in 9X13 pan
(I like to put this in the oven by itself first to toast up the bread a bit)
*a package of hot dogs, cut up
*two cans of chili (I heat first to cut baking time)
pour over bread.
Top with a drizzle of mustard (if desired),some chopped onions, and a bunch of shredded cheese. Bake.
Although this is just like chili dogs, it's easier to carry to a potluck etc.
