Shipwreck casserole is a hearty and comforting dish that combines layers of ground beef, potatoes, vegetables, and cheese. It gets its name from the idea that if you were stranded on a deserted island, this is the kind of dish you could make with whatever ingredients you have on hand. The casserole is baked until the potatoes are tender and the cheese is melted and bubbly. It's a delicious and satisfying meal that the whole family will love.
