Ingredients

• 2 cups Leftover roast (beef, pork, or chicken)
• 4 pieces Sub rolls
• 8 slices Provolone cheese
• 4 tablespoons Mayonnaise
• 2 teaspoons Prepared horseradish (optional)
• 4 pieces Romaine lettuce leaves
• 2 pieces Tomato
• 0.5 pieces Red onion
• 2 teaspoons Olive oil
• 0.25 teaspoons Salt
• 0.25 teaspoons Black pepper

Directions

Step 1

Preheat the oven to 375°F (190°C).

Step 2

Thinly slice the leftover roast into bite-sized pieces. If your roast is cold, warm it in a skillet with 2 teaspoons of olive oil over medium heat for 2-3 minutes until heated through.

Step 3

Slice the sub rolls lengthwise, but don’t cut all the way through to keep the sandwich intact.

Step 4

In a small bowl, mix the mayonnaise and prepared horseradish (if using) to create a zesty spread.

Step 5

Spread the mayo mixture evenly inside each sub roll.

Step 6

Arrange 2 slices of provolone cheese in each roll.

Step 7

Layer the warmed roast slices on top of the cheese.

Step 8

Wrap each sandwich loosely in foil and bake in the preheated oven for 5 minutes, or until the cheese is melted.

Step 9

Meanwhile, thinly slice the tomatoes and red onion.

Step 10

Once the sandwiches are out of the oven, carefully unwrap them and add a lettuce leaf, a couple of tomato slices, and a few red onion rings to each sandwich.

Step 11

Sprinkle with salt and black pepper to taste.

Step 12

Serve immediately while warm and enjoy!
