Using a food processor, pulse together the chickpeas, black beans, garlic, water, olive oil, lemon juice, chile powder, cumin and kosher salt until blended, scraping down the sides of the bowl if needed. Add the tahini, and blend for an additional 2 minutes until very smooth. Taste, and add salt to taste if needed.
