Prep: 1. Juice oranges and lime. Make: 1. Bring the orange juice, lime juice and chipotle pepper to a boil in a small saucepan. Turn the heat down to medium and simmer, uncovered, 5 minutes. Remove from heat. 2. Pour the juice mixture into the bowl of a blender and add the pico de gallo, olive oil, and salt. Puree until smooth. 3. Place the chicken in a plastic zipper-close bag, then pour the marinade over the top. Let marinate 30 minutes while grill preheats (or up to 10 hours). 4. Preheat grill. 5. Grease the grill grates and grill chicken for 5-6 minutes per side (if the breasts are very thick cover while grilling).
Because of the fresh juices in this we don't recommend marinating for much over 10 hours, but up to that long is great! Freeze the extra adobo chiles for later. Check out our favorite tips for grilling here - http://blog.gatheredtable.com/2015/06/26/barbecue-basics/
