Really? A very light sprinkle of salt when the sandwich is on the buttered griddle is the shit, especially if you’re using a cheese that is lower in salt. Get that nice crust on the bread with a savory pop. Combine that with a tomato soup and it’s the bomb.
Don’t knock it until you try it.
Edit: bloody purists. Gonna turn this into a melt/grilled cheese thing aren’t you.
