These taste best if you bake them in the oven first, but you can reheat them in the microwave. If they've been refrigerated, they only need about 30 seconds in the microwave (for 2 pieces), but microwaves can vary. If they're frozen, microwave them for about 1 minute and check to see if they're warm. Add another 10-20 seconds as needed. Be careful not to overcook them in the microwave because they may become rubbery or dry. You can also eat these cold or at room temperature.
