How to Make It
Preheat broiler to high.
Cook pasta according to package directions, omitting salt and fat; drain.
While pasta cooks, place tomatoes in a food processor; process until almost smooth. Heat a saucepan over medium-low heat. Add 1 1/2 teaspoons oil to pan; swirl to coat. Add pepper and garlic; cook 1 minute or until fragrant, stirring occasionally. Add tomatoes and 3/8 teaspoon salt; cook 15 minutes or until slightly thickened, stirring occasionally. Stir in chopped basil. Toss 1 cup sauce with pasta; keep warm.
While sauce cooks, split each chicken breast half horizontally to form 2 cutlets (4 total). Combine flour, garlic powder, and remaining 1/8 teaspoon salt. Sprinkle tops of cutlets with half of flour mixture; pat evenly onto cutlets. Turn cutlets over. Sprinkle with remaining flour mixture; pat onto cutlets. Shake off any excess flour. Place egg in a shallow dish. Combine panko and Parmigiano-Reggiano in another shallow dish. Dip cutlets in egg; dredge in panko mixture.
Heat a large nonstick skillet over medium-high heat. Add remaining 1 tablespoon oil and butter to pan; swirl until butter melts. Add chicken to pan; cook 4 minutes on each side or until browned and done. Place chicken on a baking sheet; top evenly with mozzarella. Broil 2 minutes or until cheese melts.
Arrange about 1/2 cup pasta mixture on each plate; top each with 1 cutlet and about 3 tablespoons remaining sauce. Sprinkle with torn basil, if desired.
