Heart Healthy Tuna Kebabs Recipe
In a bowl, whisk together oil, vinegar, shallots, tarragon, lemon juice and lemon zest. Add the salt and black pepper to taste. Arrange tuna in a shallow bowl. Pour half of the vinaigrette over the tuna and turn to coat. Marinate fish for 15 minutes at room temperature. Preheat grill or grill pan to medium-high heat.
Thread fish and vegetables onto 8 (12-inch) metal or wooden skewers (if using wooden skewers, soak them in warm water for 30 minutes before use). Brush the kebabs with half of the remaining vinaigrette. Grill until fish chunks are just opaque in center, turning occasionally, about 8 minutes.
In a bowl, toss the greens with remaining vinaigrette. Divide salad among 4 plates. Place skewers on greens and serve immediately.
