Begin by finely dicing the cherry tomatoes, cucumbers, roasted peppers, red onion, and parsley. Place all the diced ingredients into a large mixing bowl.

Next, roughly chop the mixed olives and crumble the feta cheese. Add them to the bowl with the other ingredients.

In a small jar, combine the extra virgin olive oil, red wine vinegar, Dijon mustard, lemon juice, dried oregano, garlic, salt, and pepper. Shake vigorously until well combined.

Pour the dressing over the salad mix in your large bowl. Gently toss until all ingredients are evenly coated.

Let the salad sit for a few minutes to enhance flavors before serving.
