Finely chop the onion and garlic. Roughly chop the collard greens. In a skillet, sauté the onions and garlic in oil for 5 minutes on medium heat. Add the collard greens and the water and sauté for 5 minutes or until the water is absorbed, stirring frequently. When the collard greens are soft, transfer to a food processor or blender. Add the remaining ingredients and blend well. Serve with crackers, rice cakes, or potato chips.
