This tastes better if you can make the garbonzos from dried beans. I put 1 cup of dried beans in the instant pot and cover them with water. Pressure cook them for 30 minutes on high pressure and natural release them for 20 minutes.
Serve 2 to 4
In a serving bowl, combine the tomatoes, olive oil, vinegar, and salt and pepper. Let sit for at least 20 minutes.
Add the Garbanzo beans, feta, onion, and cilantro to the tomatoes and mix gently. Season with additional salt and pepper, drizzle with additional olive oil, and serve.
