6 skinless boneless chicken breast halves (2 1/4 to 2 1/2 lb total)
1 cup small fresh mint leaves
2 tablespoons minced shallot
Directions
Whisk together 1 cup yogurt, 2 tablespoons oil, 1 tablespoon lemon juice, salt, and spices, then add chicken and turn until coated well. Marinate at room temperature 20 minutes.
While chicken is marinating, prepare grill for cooking. If using a charcoal grill, open vents on bottom of grill, then light charcoal. Charcoal fire is medium-hot when you can hold your hand 5 inches above rack for 3 to 4 seconds. If using a gas grill, preheat burners on high, covered, 10 minutes, then reduce heat to moderate.
While grill is heating, whisk together remaining 1 1/4 cups yogurt and 1 1/2 tablespoons lemon juice and salt to taste.
Grill chicken (discard marinade), covered only if using gas grill, on lightly oiled grill rack, turning over occasionally, until just cooked through, 10 to 12 minutes total. Transfer chicken to a platter.
Toss together mint, shallot, and remaining tablespoon oil in a small bowl. Drizzle chicken with yogurt sauce and top with mint salad.
