A controversial addition to this is … onions

As soon as I say this, most people look at me like I’m crazy and even disgusting. But the combination of thin slices of raw onion and cheese is amazing.

Most people I serve this to still refuse and say they don’t like it because of onions. But many can’t help but agree it’s a great combination.

I was convinced of this combination years ago during a holiday in southern Spain. There one of the most common cheap street food sandwiches is a fresh bun with hard manchego cheese with onions. I ate so many of them I love the combo now.
