We just make a cheese sauce with shredded cheddar cheese or use a can of cheese soup, pour over broccoli in a casserole dish, cover and bake.
Another recipe I was always asked to make at our carry in lunches @ work in MO is:
1 or 2 bags of frozen broccoli, cauliflower, carrot blend thawed out
Enough butter or margarine to grease a skillet
One half pound of American cheese per bag of veggi's
Grease a casserole dish with non stick spray
put the thawed veggi's in.
Melt the butter in skillet, and cheese (I usually cube up several slices at a time, it melts easier) When cheese is melted pour over veggi's and bake @ 350F for 30 minutes. The last 15 minutes take a sleeve of ritz style crackers and crush up, add enough melted butter to cover the crackers and put this on top of the veggi's. bake for 10-15 minutes longer. (Before adding the crackers make sure the veggis are done. I think you could substitute all broccoli for the mix of veggis. You can use fresh also if you prefer.
