Instructions

1. 1

   Turn on a multi-functional pressure cooker (such as an Instant Pot) and select Saute function. Add oil and heat until hot. Add pork cubes, working in batches if necessary, and cook until browned on all sides, about 5 minutes. Return all the pork back to the pot and cancel Saute mode.

2. 2

   Whisk together 3/4 cup water, ketchup, rice vinegar, pineapple juice, brown sugar, soy sauce, ginger, and garlic in a small bowl. Pour over pork and stir to combine.

3. 3

   Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 5 minutes. Allow 10 to 15 minutes for pressure to build.

4. 4

   Release pressure using the natural-release method according to manufacturer's instructions, about 5 minutes. Release remaining pressure using the quick-release method. Unlock the lid and remove. Transfer pork to a plate using a slotted spoon. Cover with foil to keep warm.

5. 5

   Select Saute mode and stir in onion, pineapple, and red and green bell peppers. Simmer until vegetables start to soften, 6 to 7 minutes.

6. 6

   Whisk together cornstarch and remaining 1/2 cup water in a small bowl until smooth. Pour slurry into the pot. Cook, stirring constantly, until sauce has thickened to your preferred consistency, about 2 minutes. Return cooked pork back to the pot and heat until just warmed through. Garnish with sesame seeds.
