2x 8 oz boneless, skinless chicken breasts
1/8 teaspoon salt
freshly ground black pepper
1/2 cup shredded part-skim mozzarella
slices pepperoni
slices white button mushroom
1/4 cup seasoned whole wheat bread crumbs
2 tablespoons freshly-grated Parmesan cheese
1/2 tablespoon olive oil
1 tablespoon fresh lemon juice
1/4 cup marinara sauce
8 thin slices red onion
Preheat the oven to 450°F. Line a rimmed baking sheet with foil or parchment and spray with oil.
Halve each chicken breast horizontally to create 2 cutlets. Cover with a piece of wax paper and lightly pound to a 1⁄4-inch thickness. Season with the salt and pepper.
Lay the chicken cutlets on a work surface and top each piece, with 1 tablespoon mozzarella, 2 slices pepperoni, and 2 slices mushroom. Loosely roll each one up and set them seam side down.
In a bowl, combine the bread crumbs and Parmesan.
In a second bowl, combine the olive oil, lemon juice, and pepper to taste.
Dip a chicken roll-up into the oil mixture, then in the bread crumb mixture. Place it seam side down on the prepared baking sheet. Repeat with the remaining chicken. Lightly spray the roll-ups with oil.
Bake until the chicken is nearly done, about 20 minutes. Remove the baking sheet from the oven. Top each roll-up with 1 tablespoon marinara, 1 tablespoon mozzarella, 2 slices red onion.
Bake until the cheese is melted and the sauce is hot, (5 more minutes).
