In a high-speed blender or food processor, blend together the beans, roasted red peppers, garlic, almonds, tomato paste, parsley, vinegar, paprika, and pepper flakes. With the motor running, slowly pour in the olive oil and continue to blend until a smooth sauce forms, about 30 seconds. Season with salt and pepper. Store in an airtight container in the refrigerator for up to 5 days.
