The cheese counter at the Pasta Shop in Berkeley is now offering a sandwich, a grilled cheese panini. I assume they started this pretty recently.
It's Montgomery cheddar with green onions on levain bread, flattened in a panini press, for $5. It doesn't sound like much, but it's one of the better sandwiches I've had anywhere lately. The cheese has just the right sharpness, with the onions adding flavor and texture. It's the right size, not huge but just big enough to be filling.
I had to report it here, it was that good of a find.
