Our meals are designed to be heated in the microwave since they already arrive fully cooked. You will notice instructions on each meal container regarding how long to heat the food. Slit the plastic on the top to release steam during the microwaving process and microwave for about 2 minutes. Keep in mind, though, that microwaves, unlike people, are NOT created equal, so some may require shorter or longer heating time than others. You know your microwave best, so you may want to try out your first meal assuming an average cooking time (a little under 2 minutes) and then adding to that time as you see fit.
