Recipe Tips
You don’t have to use prime rib. This sandwich will be just as delicious made with any type of leftover roast beef! Plan Ahead. While you’re picking up the prime rib from the store, grab a baguette and some fresh arugula so you’ll be ready to make these sandwiches the next day. Slice Cold. Prime rib is much easier to slice thinly when it’s cold, rather than when it’s warm from the oven. Variations: Add thinly sliced tomatoes seasoned with salt and pepper, or make a hoagie-style prime rib sandwich by layering the meat with garlic mayo, tomato, lettuce, and provolone cheese. Other Greens: Use baby spinach, chopped romaine, or any other greens you enjoy in place of the arugula if you’d like.
