Preheat oven to 375°.

Pierce eggplants several times with a fork; place on a foil-lined baking sheet. Bake at 375° for 45 minutes or until tender. Cut eggplants in half; scoop out pulp. Drain eggplant pulp in a colander for 30 minutes. Place pulp in a food processor; pulse 5 times. Add juice and next 5 ingredients (through garlic), and process until almost smooth. Remove from processor.

Combine sour cream and bell peppers in food processor, and process until smooth. Swirl bell pepper mixture into eggplant mixture, if desired. Serve with pita wedges.
