When the pot is hot add in the cubed chicken.
Sauté for about 5 minutes or until the chicken is no longer pink. Press Cancel.

To make this recipe in an Instant Pot Mini 3q, just halve all of the ingredients and cook as directed.
This recipe works great as a one-pot meal by cooking rice above the chicken using the pot-in-pot cooking method.
Keto Substitutions:
Use a sugar substitute instead of the coconut sugar
Choose a low or no sugar ketchup
Omit the pineapple chunks
Sugar and tomato products have a tendency to scorch on the bottom of the Instant Pot. To avoid this, in this recipe the sugar and ketchup is added on top of the other ingredients and not stirred into the mixture until after cooking.
The chicken in this recipe will release a lot of liquid while cooking. That plus the tamari and other sauce ingredients will be plenty for the Instant Pot to build up pressure.
