1Mix 4 tablespoons of cornstarch with 1 cup of water and set aside.
2Chop up the pork into bite-size pieces and season with salt, pepper, and minced garlic.
3Discard the water from the cornstarch mixture and keep the thick starch residue. Mix the starch residue into the pork.
4In a heated oil pan, spread out the battered pork and flatten it with a spatula until the bottom is crispy. Flip it over, press it down, and repeat until both sides are golden brown.
5While the pork is cooking, mix sugar, vinegar, soy sauce, water, and chopped bell peppers in a saucepan and bring to a boil. Add cornstarch slurry and cook until the sauce is thick.
