My family makes this every thanksgiving. Its simple and classic.
Veggie Casserole (by, mom!)
2 packages california style veggies, frozen
1 can cream of mushroom soup
16 oz sour cream
10 oz cheddar cheese (use your judgement..)
1 jar French's fried onions.
Preheat the oven to 350. Mix all but the friend onions together and put into a 9x13 casserole dish. You don't need to defrost the veggies. Cover with foil and bake in the oven for 40 minutes or until bubbly. Remove the foil and cover the casserole with the friend onions. Bake for 10 more minutes.
