1. Preheat the broiler. Combine yogurt, lime juice, garam masala, oil, honey, turmeric, salt, garlic powder and cayenne pepper in a large bowl. Make three diagonal slashes across the top of each chicken breast. Coat with yogurt mixture, massaging into slashes. Arrange chicken top side down on a foil-lined broiler pan; spray with cooking spray. Broil 4 minutes, flip, spray tops and broil 4 to 6 minutes more or until just cooked through.
2. While chicken is broiling, microwave rice and then peas according to package directions. In a medium bowl, gently combine rice and peas. Divide rice mixture among four plates. Top with chicken. Garnish with lime wedges and cilantro if desired.
