Step 1

Whisk all the marinade ingredients in a large non-reactive bowl. Add the turkey tips and toss to coat. Marinate, covered in the fridge, for at least 30 minutes or up to 2 hours.

Step 2

Whisk all vinaigrette ingredients except oil: vinegar, lemon juice, mustard, garlic, oregano, basil, salt and pepper. Slowly pour in oil while whisking constantly, to emulsify. Place cucumber, onion, peppers and tomatoes in a bowl. Pour half the vinaigrette over them and toss gently to coat. Let the vegetables marinate for 20-30 minutes.

Step 3

Preheat the grill to medium-high. Grill the turkey tips for about 5 minutes per side or until cooked through. Toss the spinach with the remaining vinaigrette and divide it among 6 plates. Add the marinated vegetables with any remaining vinaigrette, cubed feta, olives and turkey tips. Season with salt and fresh pepper, to taste.
