I have a cafe but there are no hood fans, The kitchen space is 12 x 12 and we do a good job with sandwiches and salads with a convection oven. I want to have egg sandwiches available. but all the frozen egg products are not appealing. Can I cook eggs in a muffin pan ahead of time / freeze and reheat in microwave, any other suggestions for prep or equipment??? I know you can bake liquid eggs in oven in a hotel pan but can they then be frozen and reheated?
