In a blender or large food processor combine until smooth chickpeas and liquid, red peppers, tahini, garlic, turmeric. Add black beans and lime juice, combine till smooth. If too thick, add more lime juice or water or olive oil. Salt and pepper to taste. If you like it spicier use cayenne pepper.
Serve with fresh cut vegis, crackers, pita wedges, chips... anything you like to dip.
