2 bags frozen cauliflower, cooked and drained well
3 cups shredded cheddar1/4 cup butter (you could probably use less for lower fat)
16oz sour cream
1/2 cup finely chopped onion, or 2 tbsp dried minced (or 2 tsp onion powder)
1 tsp salt or to taste
1/4 tsp pepper
Melt butter in saucepan over low to medium heat. Saute onion if you are using fresh. Add 2 cups cheese and let melt, stirring. Blend in sour cream, onion flakes or powder (if not using fresh), salt, and pepper. Fold sauce into cauliflower. Spray 9x13 casserole dish and add mixture. Top with remaining 1 cup cheese. Bake 350 for 30 minutes or more.
