Slice open the hoagie buns and lay them on a baking sheet. In a bowl combine the butter, garlic powder and Italian seasoning. Butter the insides of the bread.
Sauce the bread with the sauce in the Instant Pot. Lay cheese slices on top. Place sausage pieces on top. Cover sandwiches with foil. Bake 15 minutes. Slice and serve!
