Grilled Cheese With Peak Tomatoes
Progression of a tomato sandwich: On buttered bread with salt; on bread with mayo and cheddar; seasoned and grilled with cheddar and mayo. They’re all pretty perfect, but we’ll take the advanced version, thanks.
2 large beefsteak or other tomatoes
Kosher salt, freshly ground pepper
8 slices sourdough bread or other country-style loaf
¼ cup mayonnaise
1 pound sharp white cheddar, coarsely grated
1 small shallot, very thinly sliced
