@Chizu i can taste a hint of charcoal just looking at that.
i dont believe sliced bread is truly meant to be toasted in the first place. toasting subs after you stuff them with meat and cheese, before you toss the veggies and other condiments on? yes, absolutely. plain sliced bread like this? only way i tolerate it toasted is with enough butter to make it so soggy it may as well not be toasted in the first place.
or in grilled cheese sandwiches, but that's grilled (or pan-fried, really), not toasted, and also involves a fair amount of butter.
