Cook the pasta according to package instructions. Drain and rinse under cold water to stop the cooking process.
While the pasta cooks, chop the tomatoes, cucumber, red onion, bell pepper, and parsley into small pieces.
Add chickpeas to a large mixing bowl and combine with the chopped vegetables.
In a small bowl, whisk the olive oil, lemon juice, red wine vinegar, Dijon mustard, garlic, salt, pepper, and oregano.
Add the cooled pasta to the bowl of vegetables.
Pour the dressing over the salad and toss gently until fully coated.
Sprinkle crumbled feta cheese on top (optional) and mix lightly.
Taste and adjust seasoning if needed.
Serve immediately or refrigerate for 20–30 minutes to enhance the flavors.
