My neighbor brought this to a potluck once, and everyone immediately asked for the recipe. It’s hard to believe it only takes 4 simple ingredients

Directions:

Preheat & prep: Preheat oven to 375°F and lightly grease a 9×13-inch baking dish. Spread the frozen green beans evenly across the bottom.
Make the sauce: In a bowl, mix together the cream of mushroom soup and dry onion soup mix until well combined.
Assemble: Spoon the mixture over the green beans, spreading it loosely—it will melt and distribute as it bakes.
