Grilled Tilapia Packets with Mushrooms, Zucchini & Potatoes
Preheat barbecue to medium.
Brush foil with oil, fold in half (to crease), then open. On one half, layer potatoes, zucchini and mushrooms. Place tilapia on top of vegetables. Spoon pesto over fish; sprinkle with cheese.
Fold foil over to cover and crimp edges to seal packages. Grill packages, with lid closed, until fish is firm and opaque and vegetables are tender, 10 to 15 min. Season to taste with salt and pepper.
