For me, best sandwich ever.
Was on a junket in the US Southwest years back, a group of us hit an old time restaurant with a history. Used to be a church, then a brothel, a saloon and so on and for the most part the bones of the building were the same as in the 1800's. Hot day too as I recall so the beer was welcome. But the sandwich. My mouth waters thinking of it. Oversized bread, each slice about an inch thick, a green chili mayo with tiny flecks of jalapeno in it, ham and sharp cheese all grilled to perfection. Best taste sensation at the time and one I just wish I could duplicate.
