Sauteed-Strawberry Ice Cream Sundaes

Mix berries, sugar, and cinnamon in medium bowl; toss to coat. Heat oil in medium nonstick skillet over high heat. Add berry mixture; cook until berries begin to soften and juices are released, stirring often, about 2 minutes. Stir in orange peel. Return to same bowl and place in freezer 10 minutes to cool slightly. DO AHEAD: Can be made 4 hours ahead. Cover, transfer to refrigerator, and chill. Return sauce to room temperature or rewarm slightly in microwave-safe bowl in microwave, if desired, before serving.

Divide vanilla ice cream among 4 large wineglasses or dessert coupes. Top with scoops of strawberry sorbet. Spoon room-temperature or warm strawberry sauce over. Sprinkle with chocolate chips and serve.
