Combine 1 1/2 teaspoons oil, rosemary, garlic, salt, and black pepper in a small bowl, stirring with a whisk. Rub oil mixture evenly over chicken. Heat a large skillet over medium-high heat. Coat pan with cooking spray. Add chicken to pan; cook 2 minutes on each side (chicken will not be cooked through). Remove chicken from pan. Add remaining 1 tablespoon oil to pan; swirl to coat. Add onion, bell peppers, and mushrooms; cook 4 minutes, stirring occasionally. Add wine; cook 1 minute or until liquid is reduced by half. Stir in 1/4 cup basil, crushed red pepper, and tomatoes; cook 1 minute. Return chicken to pan; turn to coat. Reduce heat; cover and simmer 15 minutes or until chicken is done. Sprinkle with remaining 1/4 cup basil.
