Prepare the Chickpeas
Drain the can of chickpeas and rinse them under cold running water. This removes excess sodium and the starchy "aquafaba" liquid, leaving you with clean, firm beans.
Combine the Medley
In a large mixing bowl, add your chickpeas, diced avocado, crumbled feta, red onion, parsley, and mint.
Pro-Tip: To keep the avocado from browning if you aren't eating immediately, toss the avocado chunks in a teaspoon of lemon juice before adding them to the bowl.
Whisk the Dressing
In a small jar or bowl, combine the olive oil, lemon juice, minced garlic, and oregano. Whisk or shake vigorously. For the best results, let the dressing sit for about 10 minutes; this allows the garlic and oregano to infuse the oil.
The Final Toss
Pour the dressing over the salad ingredients. Use a large spoon to gently toss everything together. Be careful not to mash the avocado—you want distinct chunks in every bite.
