Allow the sauce to thicken slightly and bubble while stirring, about 2-5 minutes.
Turn off the Instant Pot, or change the setting to "keep warm."
Serve!
Notes
The frozen meatballs take about 20 minutes to come to pressure before the 5 minute cooking time. Be sure to plan accordingly!If you don't have an Instant Pot you can prepare these on the stovetop. Simple place the barbeque sauce, cranberry sauce, and veggie meatballs in a medium saucepan. Heat over medium low heat until the sauce coats the meatballs and the meatballs are cooked through in the centers. Optionally add the cornstarch slurry to thicken the sauce.
