Don't make bread an afterthought
Bread is the canvas that all sandwiches are painted on -- whether you're drizzling ketchup on your cheesesteak like a culinary Jackson Pollock or putting together a Rockwellian American club. But you don't always have to settle for the most basic bread.
"Don't be afraid to try something different if you want to switch it up," Fish said. "Making a grilled cheese? Try putting it on a bagel instead of white bread."
Fish also advised toasting both sides of your bread when making a grilled cheese, so the crunch is evenly spread and there in every bite, even on the inside.
