If you're using fresh red peppers, roast them first. Place the peppers under a broiler, turning occasionally, until the skins blister and are blackened. Let them cool, then remove the skins, seeds, and stems.
In a food processor, combine the chickpeas, roasted red pepper, tahini, olive oil, lemon juice, minced garlic, and ground cumin.
Process until smooth, scraping down the sides occasionally.
If the hummus is too thick, gradually add water, one tablespoon at a time, blending until you reach your desired consistency.
Taste the hummus and season with salt as needed. Blend again to incorporate.
Transfer the hummus to a serving bowl. Use the back of a spoon to create a swirl in the center, and drizzle a little olive oil on top.
Garnish with freshly chopped herbs and serve with pita chips, fresh veggies, or as a spread in wraps.
