Over the years 
A holiday favorite at my house, this is the casserole with minute rice, Velveeta cheese, and broccoli. This recipe is by Virginia McDowell. Jefferson City, Mo. 1975.
Broccoli and Rice Casserole
Yield: 12 servings.
1 small onion
1/2 stick butter
1 pkg. broccoli, cooked
1 can cream of chicken or mushroom soup
1/8 C. water
1/4 C. milk
1/2 C. Velveeta cheese
1 C. Minute Rice, uncooked
Chop onion fine, and cook in butter until the onions are transparent. Then mix everything together and bake for 45 minutes at 350 degrees.
I don’t care for velveeta cheese. Is there a substitution?
I might suggest using a store brand “velveeta” they don’t taste quite like Velveeta, but they do a good job of melting. Otherwise I would use a mexican blend of cheese, those melt nicely.
