Open-Faced Roast Beef Sandwich with Big Sunday Brown Gravy
Yes, they were born from leftovers, but don’t wait for the holidays to make a hot, open-faced sandwich topped with creamy mashed potatoes and hot brown gravy. Consider this recipe a road map to build a diner-style masterpiece the day after your Sunday pot roast, or whenever the craving hits. That’s because our Big Sunday Brown Gravy (along with deli roast beef and mashed potatoes) serves up a plate of comfort in a flash. A topping of buttery, bright green peas are optional–but they look pretty rad and offer a pop of sweetness that rounds out this one-plate wonder.
