If you are making these ahead of time you will stop before adding the sauce and cheese. Place in an airtight container and store in the refrigerator overnight. When you are ready to use them place them on the baking sheet and cover with sauce and cheese. You will need to cook these slightly longer to heat them through so you may want to add a little extra sauce and cheese to each to keep them from drying out. Bake for at least 10 minutes and add additional time as needed.
