Smoky charred chicken combines with bright peas and herbs in a salad that's fresh and hearty. Grilling the chicken ahead of time makes it even easier to put together.
Whisk together 1/4 cup oil, 2 tablespoons lemon juice, and 1 tablespoon garlic. Pour over chicken, and refrigerate 2 hours.
Cook peas in a large pot of boiling water until just tender, 2 to 3 minutes. Drain, and submerge in ice water to stop the cooking and retain color.
Preheat grill to medium-high heat or set up grill for indirect heat. Remove chicken from marinade, and grill chicken, turning often, until internal temperature reaches 165 degrees, 15 to 20 minutes for drumsticks and 20 to 25 minutes for breasts. Let cool, and refrigerate until ready to serve. Just before serving, cut chicken breasts into thick slices.
Whisk together remaining 1/2 cup oil, 1/3 cup lemon juice, and 1 teaspoon garlic, the shallot, mustard, salt, and chopped mint in a medium bowl. Arrange lettuce, whole mint leaves, and peas on a large serving platter. Toss chicken in dressing, and arrange on salad. Pour remaining dressing over salad.
