Drain the chickpeas and add them to a food processor along with olive oil, lemon juice, tahini, garlic, salt, and cumin.
Pulse the mixture until it reaches a smooth consistency. If it seems too thick, add a bit of water, extra olive oil, or some of the chickpea can liquid to help it blend.
Taste the hummus and adjust seasoning (salt, cumin, lemon, garlic) to your liking.
Serve the base hummus as is or proceed with one of the following flavor variations.
Remove the stem and seeds from the jalapeño. Add it along with cilantro to the food processor with the base hummus and blend until smooth.
Add the drained roasted red peppers to the food processor with the base hummus. Blend until smooth.
Thinly slice the green onions and chop the parsley. Add both to the food processor with the base hummus and blend.
