Notes
These Instant Pot Hawaiian Meatballs can easily double as a main dish and appetizer. If serving it as a main dish, we love to serve it over a bed of cooked rice. If using this as an appetizer for a party, serve with some toothpicks. They can be served directly out of your Instant Pot. You could also put them in a nice serving dish and let your guests serve themselves.
