In a large mixing bowl, combine 1 can each of drained chickpeas and cannellini beans. Next, halve a cup of cherry tomatoes, and chop half a cucumber, a quarter of a red onion, and a handful of Kalamata olives. Toss these vibrant ingredients together until well mixed.

Finely chop a handful of fresh parsley and add it to the bean and vegetable mixture. This will add a delightful herbal brightness.

In a small bowl or jar, whisk together 1/4 cup of olive oil, 2 tablespoons of red wine vinegar, 1 minced garlic clove, 1 teaspoon of oregano, salt, and pepper to taste. If you're using lemon juice, include the juice of half a lemon for a zesty kick.

Pour the freshly whisked dressing over the colorful bean mixture in your large bowl. Gently toss all the ingredients together, ensuring each piece is coated in that bright and tangy dressing.

Cover the Mediterranean Bean Salad and refrigerate for at least 30 minutes to allow the flavors to meld beautifully. Serve chilled.
