Whisk together the soy sauce, brown sugar, ketchup, the liquid from the can of pineapple slices (save the pineapple, you'll use it in step 2), rice vinegar, and minced garlic. Whisk together the cold water and corn starch til dissolved. Stir into the sauce mixture.
Lightly grease your slow cooker. Pour half of the sauce mixture into the slow cooker. Place pork chops in the slow cooker along with the pineapple slices. Pour the remaining sauce over the top. Cover and cook on high for 3-4 hours or on low 6 hours.
Serve pork chops over rice and garnish with chopped cilantro.
I used 6 thin pork chops. You'll want at least one per person, if they are thin you may want 2 per person.
