Creating the Mediterranean Chickpea Bowl can be simple if you follow these steps:

1. Prepare Ingredients: Start by draining and rinsing the chickpeas. Cut the cherry tomatoes, cucumber, red onion, and bell pepper.
2. Prepare Quinoa (Optional): If using quinoa, cook it according to package instructions. Allow it to cool before adding it to the bowl.
3. Combine Chickpeas and Veggies: In a large mixing bowl, combine the chickpeas, cherry tomatoes, cucumber, red onion, bell pepper, and parsley. If using olives and feta, add them at this stage.
4. Make the Dressing: In a small bowl, whisk together the tahini, lemon juice, minced garlic, salt, and pepper. Add water gradually until the dressing reaches your desired consistency.
5. Assemble the Bowl: Place the chickpea and vegetable mixture in a serving bowl. Add quinoa, if desired.
6. Drizzle Dressing: Generously drizzle the tahini dressing over the bowl contents.
7. Finish with Olive Oil: Drizzle a little olive oil on top for an extra flavor boost.
8. Toss and Serve: Toss all ingredients together gently before serving to ensure everything is coated with the dressing.

By carefully following these steps, you will create a Mediterranean Chickpea Bowl that is as delicious as it is healthy.
