Creating the delicious Tender Pineapple Pork in a Slow Cooker is straightforward. Follow these simple steps to achieve the best results:

1. Prepare the Pork: Trim any excess fat from the pork tenderloin and place it in the slow cooker.
2. Add Pineapple: Pour the can of pineapple chunks over the pork, including the juice for extra flavor.
3. Mix Sauce: In a bowl, combine soy sauce, brown sugar, garlic, and ginger. Stir until the sugar dissolves.
4. Combine Ingredients: Pour the sauce mixture over the pork and pineapple.
5. Add Vegetables: Layer the sliced red and green bell peppers and onion on top of the pork.
6. Set the Cooker: Cover and set the slow cooker to low for 6-8 hours or high for 4-5 hours.
7. Check for Doneness: The pork is ready when it is tender and shreds easily with a fork.
8. Thicken Sauce (optional): If desired, mix cornstarch with a little water and stir it into the slow cooker during the last 30 minutes to thicken the sauce.
9. Garnish: Once cooked, sprinkle with sesame seeds and chopped green onions before serving.
