Pork tenderloin is among the leanest meats available with just 139 calories and 4 grams of fat per 3-ounce serving. Because it contains a small amount of fat, it is important not to overcook and dry out the pork tenderloin. This cut of pork is great for an elegant-but-easy dinner!
1. In a large zip-lock plastic bag combine chipotle chilies, lime juice, onion and garlic. Add pork, then seal and marinate in the refrrigerator for 2 hours, turning the bag occasionally.
2. When ready to cook, preheat a gas grill to high or prepare a charcoal fire. Lightly coat the grill rack with cooking spray. Remove the pork from bag and discard marinade. Sprinkle the pork evenly with salt.
3. Place pork on the rack and grill over indirect heat, turning occasionally, for 20 minutes, or until thermometer inserted in the center of the pork registers 155 degrees. The inside should be slightly pink. Remove the meat from the heat and let stand 10 minutes. Slice crosswise. Serve with guacamole and tortillas if desired. Serves 6.
