I've been making this recipe for over 40 years and it's a classic for me. I got the recipe with my utility bill and it was called "Beefed Up Biscuit Casserole" but the recipe I have calls for green chilies instead of bell peppers. I use roasted chilies in this recipe and it really gives it a nice flavor. Sometimes I will also add a little Chipotle Chili powder or Cayenne powder to give it a bit more spice.
This is an oldie but goldie! I first saw it published in the Sunday newspaper supplement in the early 1970's, and still have it. It's my husband's favorite!
This is real "comfort food"...but a nice variation is mixing "white cornbread" batter
and baking the filling between two layers of this batter!!..if ya add a little chili powder, it becomes " south of the border " good!! charlielinn CA
