Start by combining the chickpeas, diced avocado, crumbled feta cheese, and thinly sliced red onion in a large mixing bowl. Toss in chopped parsley and mint.

In a small bowl, whisk together olive oil, lemon juice, minced garlic, and dried oregano. Season with salt and pepper to taste.

Pour the dressing over the salad ingredients and gently toss to combine, ensuring all components are well-coated.

Taste and adjust seasoning if necessary. Serve immediately or refrigerate to chill and allow flavors to meld.
