At this time, you can toast your buns. Warm a skillet to medium high. Spray them with cooking oil on cut/flat side (I use avocado oil spray). Then set them flat side down on the skillet for just a couple mins till they're toasted to your liking. Keep a close eye on them. Do not walk away.
Once your buns are toasted, you're ready to serve your sloppy joes as is or with your favorite toppings.
