This preparation of chicken tikka uses boneless, skinless chicken thighs and a broiler for the same effect — layered, slightly smoky flavor from charred edges of otherwise juicy, tender chicken thighs. With minimal cleanup, this dish is delicately sweet, deeply spiced and has a confetti of textures. The chicken is marinated in ginger, garlic and a mix of heady South Asian spices — red chile powder, cumin, garam masala — and yogurt is used as a tenderizer. Thirty minutes of marination does the trick but overnight is better. Bell pepper and onions sweeten during broiling and their edges char and crisp up too. Plus, juices from the spiced chicken further flavor the vegetables. Eat any leftovers in a salad or sandwich.
