Place the bell pepper skin side up on a baking sheet covered with parchment paper. Roast at 400 degrees for 10-15 minutes, or until the pepper is soft and the skin is bubbling and slightly charred. Remove from oven and cover the pepper with a lid or foil (this will allow the steam to burst the skin, making pealing it easier). Meanwhile, place the rest of the ingredients in a food processor. Uncover and peel the skin off the pepper and then place the pepper into the food processor along with the other ingredients. Blend until smooth, adding more water as necessary. Serve warm or chilled with raw vegetables, pita bread, chips, or crackers.
