4 chicken breast tenderloins (8 oz. total), halved crosswise
2 tablespoons snipped fresh basil
Lemon zest (optional)
For sauce, in a small saucepan heat oil over medium. Add onion and garlic; cook 3 to 4 minutes or until onion is tender, stirring occasionally. Stir in cauliflower and broth. Bring to boiling; reduce heat. Simmer, covered, 15 minutes or until tender; cool slightly. Transfer to a food processor. Add the water, cheese, salt and black pepper. Cover and process until smooth.
Meanwhile, cook pasta according to package directions, adding broccoli and sweet pepper the last 5 minutes. Drain, reserving ¼ cup of the pasta cooking water.
Coat a 10-inch skillet with cooking spray; heat over medium. Add chicken; cook 10 minutes or until done (165°F), turning once. Stir in sauce and pasta mixture. Heat through, stirring in enough of the reserved pasta cooking water if needed to reach desired consistency. Serve topped with basil and, if desired, lemon zest and additional cheese.
