How Do You Toast Subs?
To toast subs, preheat the oven to 350°F. Cut the sub roll and lay it open on a baking sheet. Fill it with your desired ingredients. Place the sub in the oven and bake for 5-10 minutes until the cheese is melted and the bread is lightly toasted. Alternatively, you can also toast the sub on a pan over the stove on medium heat for 3-5 minutes, flipping it occasionally until it is toasted to your liking.
