Broccoli, Cheddar and Rice Casserole

Why I Love This Recipe
This is a good way to eat all that broccoli that you need.
Ingredients You'll Need
1 (10oz pkg. broccoli florets (I also make this with California blend veggies)(I use steam in bag, but if not cook some ahead so is slightly tender before you cook in oven.)

1/2 mayo (I use Light)
1 cp. mushroom soup
1/4 cp. margarine
1/2 cp. celery (diced fine, and saute in margarine)
1/2 cp. onion (diced fine, and saute in margarine)
2 cps. rice, instant (white, or I use brown)(cooked ahead of time)
4 oz velveeta, cubed
salt/pepper
1cp. cheddar (for topping) (you can also use a breadcrumb topping(opt.) if desired)
Directions
Mix altogether execept the 1 cp. cheddar for topping
Pour into baking dish
Bake on 350 degrees for 40 min.
Remove and add cheddar and let set until cheddar melts and casserole cools some.
