Pesto Brie Chicken Sandwiches

In bowl, whisk together oil, vinegar, mustard, maple syrup, garlic, salt and pepper. Remove 2 tbsp (25 mL) and set aside for zucchini. Add chicken to bowl, turning to coat; cover and refrigerate for 2 hours, turning occasionally.

Discarding marinade, place chicken on greased grill over medium-high heat; close lid and cook, turning once, for 12 minutes or until no longer pink inside.

Meanwhile, brush 1 side of zucchini with half of the reserved marinade. Add, brushed side down, to grill; cook, covered, for 3 minutes. Brush with remaining marinade; turn and cook for 2 minutes longer or until tender and grill-marked.

Slice rolls in half horizontally. Stir together yogurt, mayonnaise and pesto; spread over cut sides of rolls. Sandwich chicken, zucchini, Brie and lettuce in rolls. Place on grill for several minutes or until rolls are crusty and heated through.
