Preheat oven to 350 degrees and grease a 9 X 13 casserole dish.
In a skillet, brown sausage until it is almost done, drain grease, then add the chopped green bell pepper and chopped onion.
In a bowl, combine all other ingredients reserving 1/4 cup of the cheese to sprinkle on top.
Add the sausage and veggies to the casserole dish, then pour the egg mixture on top and use a spoon to stir a little in the casserole dish to combine all of the ingredients.
Sprinkle the reserved cheese on top, then pop the casserole dish in the oven and bake for 30 minutes.
