Preheat your broiler.
Put on gloves. Cut the peppers in half, then remove the stems and seeds. Place the pepper halves on foil or an unlined baking sheet, cut-sides down, and place the baking sheet under the broiler. Broil the peppers for 5 to 10 minutes, until tender and well blistered, watching them closely to avoid burning.
Let the peppers cool for a few minutes while you start making the hummus.
Place the chickpeas, tahini, olive oil, lime juice, garlic, cumin, and salt into the bowl of a food processor fitted with an S-blade. Blend until smooth, adding a splash of water to help things move along if needed.
Add the jalapeños to the food processor and pulse until the peppers are chunky and distributed throughout the hummus.
Taste the mixture and add more salt if desired. Adjust any other seasonings to taste.
Spoon the hummus into a bowl or spread it on a plate, then drizzle with olive oil and sprinkle with chopped fresh cilantro, if desired. Serve with pita bread or tortilla chips.
