- 2 red bell peppers, seeded and cut into strips
- 4 medium zucchinis, halved lengthwise and sliced
- 4 tablespoons olive oil, divided
- salt
- freshly ground black pepper
- 2 large red onions, sliced into thick rings
- 1/2 cup mayonnaise
- 6 cloves garlic, minced
- 2 tablespoons lemon juice
- 1 tablespoon dried oregano
- 1 loaf focaccia bread, quartered and split horizontally
- 6 ounces crumbled feta cheese
- Preheat the grill for high heat.
- Place bell peppers and zucchinis in a medium bowl. Drizzle with 3 tablespoons oil and season with salt and pepper; toss to coat.
- Place onion slices on a plate; coat with remaining tablespoon of oil and sprinkle with salt and pepper.
- Place vegetables on hot grill, cover and cook, turning once until vegetables have grill marks and are tender crisp, about 6-8 minutes. (The onions may take longer. If so, let them grill along with the bread.) Remove vegetables from grill and set aside.
- In a small bowl, mix the mayonnaise, garlic, lemon juice and oregano. Spread a portion of the mixture over the cut sides of the bread and sprinkle each one with feta cheese.
- Reduce heat to low and place bread, cheese side up, on hot grill; cover and cook until crisp on the bottom and warmed through, about 2 minutes. Remove from grill.
- Arrange a portion of vegetables on each slice of toasted focaccia bread, beginning with onions, then zucchinis and finally bell peppers. Serve open-face.
