Mandarin oranges get the spicy treatment when chipotle in adobo is added. This citrus-forward relish works great as a burger topper.
Drain oranges, reserving 2 tablespoons juice in medium bowl. Discard remaining juice. Roughly chop oranges and add to bowl.
Add onion, cilantro, lime juice, oil, chipotle pepper and salt; mix well. Cover and refrigerate at least 1 hour to allow flavors to blend. Serve cold.
