2 (15 ounce) cans cut green beans, drained
1 (10.5 ounce) can condensed cream of mushroom soup
¾ cup milk
1 (2.8 ounce) can French fried onions
salt and pepper to taste
Preheat the oven to 350 degrees F (175 degrees C).
Mix green beans, cream of mushroom soup, milk, and 1/2 of the fried onions in a medium casserole dish.
Bake in the preheated oven until heated through and bubbly, about 25 minutes. Sprinkle remaining onions over the top, and return to the oven for 5 minutes. Season with salt and pepper to taste.
