In a food processor, combine the beans, parsley, olive oil, lemon juice, curry powder, cumin, salt, cayenne pepper, garlic and lemon zest. Blend until smooth. Season with salt. Pour the dip into a serving bowl and serve with Whole Wheat Pita Chips alongside.
Preheat the oven to 350 degrees F. Cut each pita bread into 8 wedges. Arrange on a baking sheet and drizzle with the olive oil. Sprinkle with the salt and pepper and bake until crisp and golden, 12 to 15 minutes.
