This came from an old Betty Crocker Cookbook. It looks a bit intimidating, but is actually fairly quick and easy. I use Turkey Kielbasa and low fat cheese.
Cook and stir sausage, chilies, chili powder, oregano, seasoned salt, cumin, garlic powder and sugar in oil in a 12 inch skillet until sausages are light brown.
Stir in corn and mushrooms.

Heat oven to 400.
Heat butter in a 9 inch deep dish pie plate until melted.
Beat eggs, flour and milk until smooth.
Pour into pie plate.
Mound sausage mix into pie plate to within 1 inch of edge.
