Begin by preparing the pork and marinade for 15-20 minutes.
Prepare the veggies, fruits & aromatics. Also combine the sweet & sour sauce ingredients in a medium bowl, excluding the tomato paste.
After the pork has marinated, add the rice flour to a plastic gallon storage bag with the pork. Seal and shake until the pork is well coated.
In a large heat safe pot or skillet, add cooking oil for a shallow fry. The oil should get warmed to 150 degrees and add the pork pieces and fry until golden brown on all sides. Note, you will need to flip the pork so it cooks on all sides.
Once cooked, transfer out to paper towels or drying rack and salt lightly.
Now onto creating the dish! Warm a wok or non stick pan to medium-high with a touch of cooking oil. Add the peppers and stir fry for 2 minutes. Add the onions (note: reserve the green onion tops) and cook for another minute or two. Add the pineapple and garlic and continue to stir fry for a few seconds, careful not to burn the garlic.
Now add the tomato paste and cook off for 1-2 minutes. Add the remaining sweet & sour sauce ingredients and continue to stir fry. Note: If the sauce looks really soupy, add a cornstarch slurry.
Add the pork and stir fry until well coated. Finish with the green onion tops.
Serve with rice, enjoy & cheers 🥂🍻!
