"Made this for the guys down at the firehouse and they all loved it. Made a few alterations though. Used 6 eggs instead of 4.

"This is a really great recipe. It is versatile by allowing the cook to add whatever ingredients (meat, veggies) that is desired. That aside, it does have a tendency to come out a bit more running th..." See morean most breakfast casseroles. To alleviate this problem, I use a 16oz bag of herb seasoned croutons. I also like my casseroles a bit more meaty and cheesy. Therefore, I use 1 pound of turkey sausage and 1 pound of bacon along with 16oz of shredded cheese. I also add a bit of paprika to the mix. The eggs and milk provide ample moisture for the crouton mixture to bake up moist but not soggy. As for execution, I mix everything except the croutons together and then mix in the croutons so that the add-ins are distributed throughout the casserole. Then I pour everything into a 9x13 baking dish. I take this casserole to MOPS (Mothers of Preschoolers) everytime it is my turn to cook and I never come home with any left overs."
