Add the pork tenderloin to the crockpot and pour the teriyaki sauce over it. Using a tong, turn the tenderloin to coat it in the sauce. Reserve a few pineapple chunks for garnishing the dish, and pour the rest, including the juices, into the insert alongside the tenderloin.
Cover and cook on high for 2 to 2 1/2 hours or on low for 4 hours or until the pork reaches 145°F and is tender.
Remove the tenderloin to a serving platter, cover, and let rest 10 to 20 minutes. Meanwhile, whisk together the cornstarch slurry. Turn the crockpot to high and stir in the cornstarch mixture. Cover and let the sauce thicken while the tenderloin rests.
Notes
To Serve
This dish is incredibly versatile. Here are some ideas:
Pineapple Pork Bowls, slice (or shred), and serve over coconut rice, topped with jalapeno for added heat, fresh cilantro, a squeeze of lime juice, and even crunchy onions if you have them handy.
Sliders: shred the tenderloin and pile it onto slider buns.
Pineapple Tacos: Add meat to crispy taco shells and serve with greens, fresh cilantro, pineapple chunks, sliced red onion, and hot peppers for additional heat if you like.
