Green bean casserole is a classic dish that is perfect for holidays or any special occasion. To make this dish, preheat your oven to 350°F. In a large bowl, mix together canned cream of mushroom soup, milk, soy sauce, black pepper, and green beans. Pour the mixture into a casserole dish and top with fried onions. Bake for 25-30 minutes, or until the casserole is hot and bubbly. Serve and enjoy!
