Preheat the grill to high.
Brush the cucumbers, peppers and onions with olive oil, and sprinkle with salt, pepper and oregano. Be sure to get both sides.
1 red onion, 1 cucumber, large, 2 red bell peppers, large, 1/4 cup olive oil, 1/2 tsp salt, 1/2 tsp coarse ground black pepper, 1 tsp Greek oregano
Add the veggies to the grill and cook, about 10 minutes on each side until nicely charred.
While the veggies are grilling, prep the rest of the salad. Toss together the chopped lettuce, tomatoes, olives and feta cheese.
1 head romaine lettuce, 2 roma tomatoes, 2/3 cup feta cheese, 1/4 cup kalamata olives
When the veggies are done, remove from the grill and cut them into pieces as large as the tomatoes and cheese for uniformity. Squeeze everything with lemon juice. Toss thoroughly and serve immediately.
