For the chimmichurri, place the olives, parsley, oil, garlic, lemon juice and 5 tablespoons water in a small bowl or jug. Using your stick blender puree to a chunky paste. OR puree in your food processor or regular blender. Taste and season with salt if needed (you might not depending on how salty your olives are). Set aside. If using beans, trim to remove stalks but leave the tails intact.
