High Protein Tomato Mozzarella & Arugula Sandwich

Lunch

This vegetarian sandwich is packed with protein, thanks to creamy fresh mozzarella cheese and plenty of walnuts blended into the roasted red pepper spread. The spread, reminiscent of romesco sauce, is versatile and can also be served as a dip or sauce—adding depth and complexity to dishes like grilled meats, seafood and vegetables—or as a topping for pasta.

Ingredients

1 cup roasted red peppers, plus 1 tablespoon liquid from jar, divided
1 cup walnuts
1 tablespoon red-wine vinegar
1 teaspoon paprika
1/2 teaspoon garlic powder
4 (3-ounce) ciabatta rolls, split horizontally
2 cups loosely packed baby arugula
1/2 cup thinly sliced red onion
8 (1-ounce) slices fresh mozzarella cheese
1 medium tomato, cored and cut into 8 (1/4-inch) slices
1/4 teaspoon salt

Description

Combine roasted red peppers, walnuts, vinegar, paprika and garlic powder in a food processor; process until a slightly chunky spread forms, 2 to 3 minutes, stopping to scrape down sides as needed and adding liquid from the pepper jar, 1 teaspoon at a time, as needed to help puree the mixture.
Spread the pepper mixture evenly on cut sides of ciabatta rolls (about 2 tablespoons each). Top each bottom slice with 1/2 cup arugula, 2 tablespoons sliced onion, 2 mozzarella slices and 2 tomato slices. Sprinkle with salt. Top with the remaining ciabatta slices. Cut the sandwiches in half and serve.
