In a large mixing bowl, add the rinsed and drained chickpeas, cubed ripe avocado, crumbled feta cheese, thinly sliced red onion, chopped parsley leaves, and chopped mint leaves. Gently mix these ingredients together, ensuring the avocado holds its shape.
In a small bowl or jar, whisk together the olive oil, fresh lemon juice, finely minced garlic, and dried oregano. Season the dressing with salt and pepper to taste. I like to use freshly ground black pepper for an extra punch of flavor.
Pour the lemon-oregano dressing from Step 2 over the salad ingredients from Step 1. Gently toss everything together until well combined and all ingredients are evenly coated with the dressing. Be careful not to mash the avocado or feta while tossing.
Serve the salad immediately or cover and refrigerate for later enjoyment. Chilling it for about 30 minutes can help the flavors meld beautifully. For a brighter touch, I sometimes add a few extra parsley leaves on top before serving.
