You have a large amount of food that you have to prepare, you are having a hard time trying to figure out how to keep it all warm. You might have a bit of trouble finding all of the supplies, but this tip will help you keep it all warm.
Find a box that is large enough to hold all of your food with plenty of room to spare.
Now locate some thick foam insulation boards. You can find these at your local home improvement store.
Cut the pieces to line all sides of your box and a piece for the top.
Now cover the whole inside with aluminum foil.
When you have your box prepared, just drop in all the food and place on the lid and your food will be kept toasty warm for hours.
