Add pecans to food processor but save a couple for garnish. Pulse till finely chopped. Leave in processor bowl.
Add the rest of the ingredients to food processor saving water for last. Add the water one tablespoon at a time and pulse until you reach the right consistency. If you like a creamier hummus, just add more water.
Top with whole or crushed pecans. Serve as a dip for vegetables, tortilla chips or as a spread for a pita sandwich.
