Grilled Marinated Tuna - cooking recipe

Ingredients

3 lb. fresh tuna
2 garlic cloves, crushed
1 medium onion, finely chopped
1 tsp. dried oregano or marjoram
1 tsp. coarsely ground pepper
1 1/2 c. robust red or dry white wine
1/2 c. olive oil
1 bay leaf
1 (2-inch) strip orange rind
2 to 3 medium zucchini, cut crosswise into 1/2-inch rounds

Preparation

Trim away any dark red portions of the tuna.
Cut the tuna into 1 1/2-inch squares and place in
a nonmetallic bowl.
Add the garlic, onion, oregano and pepper and toss well, rubbing the seasonings into the fish.
Add the wine, oil, bay leaf and orange rind and turn the fish to coat with this mixture.
Marinate for 30 minutes at room temperature.
Prepare the grill.
Thread alternating pieces of the tuna and zucchini snugly on skewers. Grill about 5 minutes on each side, brushing occasionally with the reserved marinade, until lightly browned.
Serve immediately.
