In this great country of ours, one could eat a different sandwich every day of the year—so that's what we'll do. Here's A Sandwich a Day, our daily look at sandwiches around the country. Got a sandwich we should check out? Let us know. —The Mgmt.

I think I may make it a new rule of thumb to order Mediterranean-style tuna salad whenever I see it on a menu. Using olive oil as a bind instead of mayonnaise, tuna salad becomes a light, refreshing lunch, rather than a gloppy pile of well, fishy-tasting fish.

The tuna nicois sandwich ($7.75) at Brioche Bakery is a particularly excellent example of just how good this can be. Diced-up olives added an excellent salty tang to the (very fresh) tuna; served with meaty slices of tomato on an excellent, crusty baguette, this sandwich made for an excellent sunny-day lunch. I requested mine with Dijon mustard; the spicy spread did wonders for the sandwich's overall flavor.
