1. Place pork roast in self-sealing plastic bag. In food processor, place parsley, onion and garlic and pulse until minced. Add remaining ingredients, except garnish, and process to blend. Coat pork in plastic bag with this mixture. Seal bag and refrigerate overnight.
2. Prepare medium-hot fire in grill. Remove pork from marinade (discard marinade) and place pork roast over drip pan on grill over indirect heat. Close grill cover and cook about 1 hr. (20 min. per pound), until internal temperature on a thermometer reads 145°F. Remove roast from heat; let rest about 10 min. before slicing. Garnish with lemon and lime slices.
