Cut slits in the pork roasts and stuff the slices of garlic in the holes. Do this with all the garlic slices all around the roast.
Add the olive oil to a large pan and heat to medium high.
Brown the roast on all sides. About 2-3 minutes on each side. Then set aside.
To the slow cooker add your onion, bell peppers, chipotle peppers and apple cider vinegar and stir well.
Place the roast on top of the vegetables and cook for 6-8 hours until the meat can fall apart with a fork.
When down, shred the pork in the crock pot and mix well into the vegetables and sauce.
Serve with the limes so that everyone can sqeeze some lime juice over their dishes before eating.
Eat over rice or in tacos or burritos. Garnish with avocados, cilantro, sour cream, cheese or whatever you like.
