1. Prepare the Salad Base: In a large bowl, combine the mixed greens, strawberries, blueberries, and raspberries. Gently toss to mix the ingredients.
2. Add Optional Ingredients: If desired, sprinkle the crumbled feta cheese and chopped walnuts or almonds over the top for added flavor and crunch.
3. Make the Creamy Dressing: In a separate bowl, whisk together the Greek yogurt, olive oil, honey or maple syrup, lemon juice, garlic, oregano, salt, and pepper until smooth and creamy.
4. Combine: Drizzle the dressing over the salad just before serving, and toss gently to ensure the greens and berries are well coated.
5. Garnish: Add fresh mint leaves on top for a delightful aroma and color.
