In a food processor, combine the chickpeas, tahini, olive oil, garlic, lemon juice, ground cumin, and a pinch of salt. Blend until smooth.
If the hummus is too thick, gradually add water, one tablespoon at a time, until the desired consistency is reached. Taste and adjust the seasoning if necessary.
In a large serving bowl, layer the cooked quinoa as the base.
Spoon the prepared hummus over the quinoa, creating a generous layer.
Arrange the cherry tomatoes, cucumber, bell pepper, and red onion on top of the hummus.
Drizzle the olive oil over the vegetables and sprinkle with chopped parsley, salt, and pepper to taste.
Serve immediately and enjoy your nutritious hummus bowl!
