My sister-in-law served this at a family function and it's been a hit ever since. No Cheese Whiz, just real cheddar cheese. Delicious, and kid-friendly. My now-grown son would request this when he came home from college. This recipe is very adaptable as well - add crushed Ritz crackers or panko crumbs on top during the last 5 minutes of cooking for a crunchy topping. Add bacon bits to the mixture for some extra flavor, or add a couple teaspoons of hot sauce for some heat. I also have used brown rice successfully with this recipe, and frozen broccoli cuts instead of chopped.
