1 (16 oz.) pkg. California Blend vegetables
1 can golden mushroom soup
4 oz. Velveeta cheese
1 can French fried onion rings
1/2 stick butter

Mix first three ingredients in baking dish. Drizzle butter over all. Bake 1 hour at 350 degrees. During last 10 minutes of baking, put onion rings on top. (I like to mix 1/2 of the can in first three ingredients and only use 1/2 on top.)
