SKINNY GRILLED CHICKEN SANDWICHES WITH LIME DRESSING

Steps:

• For lime dressing: In a small bowl, combine mayonnaise, lime peel, and salt. Cover and chill until serving time.
• Brush zucchini slices with 1 tablespoon of the Worcestershire sauce and the olive oil; set aside. Brush all sides of the chicken with the remaining 2 tablespoons Worcestershire sauce.
• For a charcoal grill, place chicken on the rack directly over medium coals. Grill, uncovered, for 12 to 15 minutes or until juice of chicken is clear when center of the thickest part is cut (165°F), turning once halfway through grilling. Add zucchini slices to grill for the last 6 minutes of grilling time, turning once and grilling until zucchini slices are softened and lightly browned. (For a gas grill, preheat grill. Reduce heat to medium. Place chicken on grill rack. Cover and grill as above, adding zucchini as directed.)
• To serve, spread lime dressing on cut sides of toasted buns. If desired, halve zucchini slices crosswise. Place chicken, tomato slices, and zucchini slices on bun bottoms; add bun tops.
• *For added color, use half of a medium zucchini and half of a medium yellow summer squash.
