You can use any meat with this marinade. I have tried it with beef, pork, and even seafood. This recipe is directly from the Founder, CEO, and Chef of Chipotle Mexican Grill. I hope you enjoy it as much as I do!
Soak dry chiles in water overnight or until soft. Remove seeds. Add all ingredients except meat in food processor. Puree until smooth.
Spread mixture over meat and refrigerate at least one hour, up to 24 hours.
Heat grill to about 400 degrees, or if cooking inside heat small amount of oil in skillet or grill pan over high heat. Salt meat to taste. Grill meat about 4 minutes per side, depending upon thickness, until done.
