heat the weed up in a frying pan(maybe with a tad of oil) make sure you dont turn the weed brown or black or anything just heat it up enough to let out the thc, put the weed and oil into your se=andwich and proceed to cook it like a regular grilled cheese(ecxept put the heat lower and take a longer time with it)....it should work fine but it'll probably make your house smell any way you do it.
