Cook orzo according to package directions. In the meantime wash and chop the lettuce, tomatoes, and cucumbers.
Prepare the salad by combining the lettuce, cooked orzo, cabbage, tomatoes, and cucumbers together. Top with crumbled feta.
Whisk together the olive oil, balsamic vinegar, lemon juice, garlic, oregano and salt and pepper until combined.
Cut the tops off of the peppers and remove the inside stems and seeds.
Drizzle the dressing over the salad and use tongs to scoop the salad into each of the cleaned out peppers.
Eat with a fork right out of the pepper, or lay the pepper on its side and use a knife to cut it into strips, so that the pepper is combined with the salad. Enjoy!
