You can store the assembled rolls unbaked and tightly wrapped in the fridge for 24 hours. Once baked, let it cool. Portion the rolls out into airtight containers or cover the whole dish tightly in plastic wrap for up to 4 days. To reheat, you can microwave individual rolls. If you are reheating a large portion, you can do so in the oven in a baking dish. Bake at 350F until warmed through.
