Cooking time depends on the size of the burrito and the wattage of your microwave.For most 4 oz Tina’s Burritos, remove the wrapper, place the frozen burrito on a microwave-safe plate and heat on HIGH for approximately 35 seconds. Turn it over and heat for another 35 seconds. Let it stand before eating because the filling may be very hot.Tina’s Big Burritos require additional cooking time and are generally ready in about two minutes.Microwave ovens vary, so always follow the cooking instructions printed on your individual package and make sure the center is hot before eating.
