In a skillet brown the ground beef until halfway cooked through, drain off fat and liquid.
Add the onion, green pepper, garlic, cumin, chili powder, salt, and pepper to the meat. Continue to cook until the ground beef is no longer pink and cooked through.
Place the meat and vegetable mixture into a square 9-inch casserole dish.
Place eggs into a bowl and whip with a whisk to combine.
Pour eggs over the meat mixture and cover with a lid or foil.
Bake for 25 minutes, then uncover the casserole dish and bake for another 15 minutes, until eggs and set and cooked through.
Serve with cheese and sour cream on top if desired with a salad to make a complete meal.
Notes
If your family won't eat peppers or onion you can use a different vegetable instead.
