Rinse pork chops and pat dry. Season both sides with salt and pepper and sear in olive oil in a large skillet over medium-high heat. Leave in skillet only until nicely browned on the first side then remove from skillet and set aside. If the chops are too large, do this step in batches.
Combine the black beans, green chili tomatoes, corn, onion and all of the spices in a large mixing bowl. Cover bottom of slow cooker with 1/3 of the bean mixture. Place two chops on top with browned side up. Repeat with half of remaining sauce, final two chops, ending with sauce.
Turn cooker to high for 2½ hours or low for 5 hours. When chops are done, squeeze lime juice into sauce and garnish each serving with chopped cilantro after spooning vegetable mixture over each chop.
If you prefer canned corn, simply swap it out with the frozen corn the recipe calls for.
