This makes flavorful tacos. Make sure to cut up some of the grilled pineapple and put it in your taco with the meat. I sometimes make this using my grill pan. Recipe from Tacos by Susan Curtis and Daniel Hoyer.
Arrange slices of pork on a cutting board or smooth countertop between layers of plastic wrap. Using a meat-tenderizing mallet or a rolling pin, flatten the slices to form sheets about a quarter inch thick.
Place chiles, onion, garlic, achiote, vinegar, honey, cilantro, oil, water, cloves, salt, and pepper in a blender and puree smooth.
Spread mixture evenly over the sheets of pork and marinate in refrigerator for 1 to 3 hours. Remove from refrigerator 1/2 hour before cooking.
Preheat a charcoal or gas grill or oven broiler to produce a medium-high heat.
Place pineapple slices on grill alongside the marinated pork. Cook about 3 to 4 minutes on one side and turn over. Continue cooking until slightly charred and cooked through.
Remove from heat, cover and allow to rest for 5 to 10 minutes. Cut pork in quarter-inch strips. Garnish: pineapple may be sliced small as well or served in large slices.
Arrange on soft corn tortillas and top with garnishes.
Serving suggestion: Serve with refried beans, Mexican rice and an assortment of condiments such as roasted jalapeno chiles, salsa, Mexican cheese, avocados, grilled onions, lime, and toasted oregano.
