Waffles are previously cooked and frozen. These take a few minutes in a regular oven at 375 to reheat. Bacon and sausage is previously cooked and refrigerated and take very little time to reheat in a microwave.

My challenge is that I have a proofing box with sterno at the facility to use. Not familiar with using these to reheat refrigerated/frozen items. What temp should I heat the box to? How do you effectively regulate/control the temp? How long will it take to preheat? What kind of time frames am I looking at to reheat the food this way? (18# bacon, 8# sausage, 250 waffles)

Also making hash browns and eggs in roaster ovens.
