4th of July Breakfast Casserole

This is the casserole my Mom would always make for the 4th of July breakfast with our church. Just eating it makes me want to hop on my decorated bike and cruise around the park in parade fashion with the other kids.

K, not really... but it's good and super easy. And SO good when you're feeding a large group for breakfast.

1 ½ lbs. sausage
9 eggs
Grated cheddar cheese
3 c. milk
3 slices bread, cubed
1 t. salt
1 ½ t. dry mustard
Pepper
1 can chopped green chilis (optional)

Brown sausage. Mix all ingredients. Pour into 9x13 pan. Bake uncovered at 350 for 1 hour.
