Grab a big bowl and dump in the chickpeas. If you’re using canned, give them a good rinse to rattle off that briny vibe.
Add tomatoes, cucumber, red onion, olives, and parsley. Give everything a quick toss so colors mingle like a good group chat.
Crash in the olive oil, vinegar or lemon juice, oregano, and a pinch of salt and pepper. Toss again until the dressing coats every ingredient.
Sprinkle feta on top, unless you’re dairy-free, then skip it and pretend it’s a feta-flavored dream. Add chili flakes if you want a little heat.
Let it rest for 10 minutes if you can wait. The flavors grab hands and waltz together. Serve chilled or at room temp.
