grilled sandwich tip

did you know that if you put a light layer of mayo on the outside of your bread slices when making a grilled cheese (or other kind of grilled sandwich) you will end up with a more deliciously crispy and less greasy sandwich?!?! it's better than using butter because you don't have to wait for it to soften, and maybe it's healthier. it tastes real good, though. and the crispiness factor is upped at least 10 points.
