If any roast beef survived the Christmas feast, here are genius tricks for upgrading leftovers from F&W Test Kitchen pro Kay Chun.
1. Homemade Beef Broth. Sauté chunks of roast beef with a chopped onion until golden, then add water and simmer for a light beef broth.
2. Minute Steak Sandwiches. Fry thin slices of beef in a skillet and arrange them on a baguette. Top with sautéed onions and cheese, and toast under the broiler until the cheese melts.
