Good old Bisquick!  Feel free to vary this (leave out the broccoli)- add spinach, bacon, ham, taco meat, diced chils, mushrooms, different cheese, whatever.  It all works!  Bonus – it can be made the night before and refrigerated.  Just cook a little longer.  See Impossible Ham and Swiss Cheese Quiche for smaller quantities. 

Ingredients:

• 9 c Bisquick (1 box = 8 c)
• 3 qt milk
• 2 ct Easy Eggs (1 carton = 18 eggs)
• 5# cheddar cheese – grated
• 90 oz broccoli, chopped – frozen
• 4 c diced onion – frozen
• 1 t salt
• ½ t pepper

Directions:

1. Heat oven 400°.
2. Really Pam 6 small foil pans. (1/2 steam table size, approx 9×11.  The center does not cook enough in larger pans.)
3. Thaw and drain broccoli – squeeze dry.
4. Mix eggs, milk, Bisquick, salt, pepper
5. Add broccoli, onion and 3# cheese
6. Pour into pans.
7. Bake 35 to 45 minutes (maybe longer) until knife comes out clean.
8. Top with remaining cheese.
9. Bake until cheese melts.
10. Let sit for 5 minutes before serving.

Serves:  48 (cut 2×4) or 70 (cut 3×4)
