Preheat oven to 400°. In a large skillet, cook beef over medium heat 10-12 minutes or until no longer pink, breaking into crumbles; drain. Add taco seasoning and prepare according to package directions. Spoon meat into a greased 13x9-in. baking dish.
In a large bowl, beat eggs and milk. Stir in biscuit mix and pepper. Pour over meat. Bake, uncovered, 20-25 minutes or until golden brown. Cool 5-10 minutes.
Spread sour cream over top; sprinkle with lettuce, tomato, green pepper, onions and cheese. Freeze option: Cool baked casserole; cover and freeze. To use, partially thaw in refrigerator overnight.

"Migas" means "crumbs" in Spanish. For a migas twist, swap a cup of torn tortillas or coarsely crushed tortilla chips for the biscuit mix. Then bake till set (it may take a little longer).
For individual portions that kids will love, bake in greased muffin cups until golden brown, 15-20 minutes.
