High-Protein Tomato, Mozzarella & Arugula Sandwich

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

Instructions

1. 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.
2. 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. Additional reporting by Carrie Myers, M.S. and Linda Frahm
