INGREDIENTS- 3 tbsp. extra-virgin olive oil, divided
- 2 tbsp. red wine vinegar
- 1/4 small red onion, thinly sliced
- 2 tbsp. fresh oregano leaves
- Kosher salt
- Freshly ground black pepper
- 3 (8-oz.) tilapia filets
- 1/2 c. grape tomatoes
DIRECTIONS- Preheat grill to medium-high heat. In a medium bowl, whisk 2 tablespoons olive oil with red wine vinegar. Add red onion and oregano and season with salt and pepper.
- Brush tilapia with remaining olive oil and season with salt and pepper. Place filets and grape tomatoes on preheated grill. Cook grape tomatoes until soft and blistered, about 4 minutes total. Grill tilapia until edges are opaque and the flesh releases easily from the grill, about 4 minutes per side.
- Remove fish onto serving plate. Toss grilled tomatoes with vinegar mixture and spoon over filets. Serve immediately.
