1-First: rinse the cucumber, green pepper, cherry tomatoes, red onion, and mint leaves under cold water and pat them dry.

2-Next: prepare the dressing by whisking ¼ cup olive oil, 3 tablespoons red wine vinegar, 1 minced garlic clove, ½ teaspoon dried oregano, ¼ teaspoon Dijon mustard, ¼ teaspoon salt, and ¼ teaspoon pepper in a small bowl.

3-Assembling and Serving: Arrange the 1 English cucumber (cut lengthwise, seeded, and sliced ¼-inch thick), 1 green bell pepper (chopped into 1-inch pieces), 2 cups halved cherry tomatoes, 5 ounces feta cheese (cut into ½-inch cubes), ⅓ cup thinly sliced red onion, and ⅓ cup Kalamata olives on a plate. Drizzle the dressing over the top and gently toss everything to coat. Sprinkle a bit more dried oregano and add ⅓ cup fresh mint leaves just before serving to keep it fresh.

4-Adjust seasoning to taste and serve right away. This method takes about 15 minutes total and serves 4, making it perfect for quick meals. For variations, try different bell peppers or fresh herbs, and remember tips like using cherry tomatoes to avoid excess water and seeding the cucumber to prevent sogginess.
