Breakfast (Casserole) for Dinner

My mother hates to cook. She fed us only because we would die without food while growing up. But one of her staple meals was breakfast for supper (as we called it in Southern Alabama). My mom's usually consisted of fried eggs and cheese toast. My own variation of it for tonight was a tad more complicated, but not much:

Breakfast Casserole
1/2 lb. Conecuh (or other) sausage
1/2 yellow bell pepper, diced
1/2 onion, diced
1 zucchini, cut into small pieces
4 hot dog buns, torn into small squares (buns are left-over from Labor Day gathering)
8 eggs
1/2 cup milk
1/3 cup plain yogurt
1 slice provolone cheese
1 slice American cheese
1/3 cup spinach, shredded

Spray 9 x 13 pan with non-stick spray.

Place torn bread in pan.

Brown sausage, adding bell pepper, onion and zucchini and sauteing until soft.

Pour sausage and veggie mixture over bread.

Scramble eggs, milk and plain yogurt. Pour over other ingredients.

Tear cheese slices into squares and place over casserole. Top with shredded spinach.

Bake at 350 for 45 minutes to an hour.
