HOT ROAST BEEF SANDWICHES WITH GRAVY RECIPES

Steps:

• Preheat the oven to 350 degrees F.
• Mix together the mayo, mustard, poppy seeds, grated onion, horseradish mayo and Worcestershire. Taste the dressing and adjust the ingredients however you wish.
• To assemble, spread the dressing on the top and bottom buns. On the bottom bun, lay on some provolone, roast beef and American cheese, and place the top bun on top. Repeat with the next sandwich.
• Wrap each sandwich in a foil square, and either bake right away or keep in the fridge. To bake right away, put them on a baking sheet in the oven until the buns are slightly crusty and the cheese is melted, 15 to 20 minutes. Great for a crowd!

Steps:

• In a small bowl, mix together the onion and 1 tablespoon of the salt. Set aside for 20 minutes. Rinse the onions with cold running water. Drain and squeeze to remove excess liquid. Combine the onions and the vinegar and marinate at least 30 minutes or up to 24 hours.
• In a small bowl, mix together the mayonnaise, sour cream, horseradish, zest, and 2 teaspoons salt. Season generously with pepper and hot sauce to taste. Refrigerate the horseradish sauce for at least 30 minutes.
• Preheat the broiler. Slice the rolls in half lengthwise. Using your hands, shallowly scoop out the inside of each half. Transfer the rolls to a baking sheet and arrange scooped-side up. Toast the rolls under the broiler for about 1 minute. Slather the inside of the rolls with the horseradish sauce. On each of the roll bottoms, layer 2 tomato slices and season with salt and pepper to taste. Top the tomatoes with some of the roast beef overlapped into "ruffles" and season with salt and pepper. Top the meat with some of the onions and watercress and cover with the tops of the roll. Serve immediately.
