Step 1

Turn on a multi-functional pressure cooker (such as Instant Pot®) and select Saute function. Add oil once the pot is hot.

Step 2

Sprinkle both sides of pork chops with salt, garlic, and pepper. Sear pork chops in the hot oil until golden brown, 2 to 4 minutes per side. Add soy sauce, water, rice vinegar, honey, coconut sugar, ginger, and garlic. Mix to combine. Cancel Saute function.

Step 3

Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 8 minutes. Allow 10 to 15 minutes for pressure to build.

Step 4

Release pressure using the natural-release method according to manufacturer's instructions, about 15 minutes. Release remaining pressure carefully using the quick-release method, about 5 minutes. Unlock and remove the lid.

Step 5

Pour 1/3 cup pineapple juice from the can into a small bowl. Add cornstarch to make a slurry.

Step 6

Remove pork chops from the pot and cover to keep warm.

Step 7

Stir slurry into the liquid in the pot. Select Saute function and cook, stirring frequently, until sauce thickens, about 3 minutes. Add 1 pineapple ring per pork chop to the sauce. Serve each pork chop with 1 pineapple slice and teriyaki sauce.
