I was late to the party. I discovered them back in March of 2009, on the old Lala music store that Apple bought. On the sandwich front, you can also use herbed butter, but you'll want to be on top of things so as not to burn it. If not baking ourselves, there's a very nice bakery in the city that does a lovely personal size focaccia which makes for a wonderful "slim" sandwich. Calling it slim would be deceptive. I've had some lovely rustic breads from bakeries in Sonoma and Napa counties. There was one in Del Norte county that did something quite extrodinary with olives and olive oil, but I can't recall the name nor the city within the county. Most likely because I'd gone there a few weeks prior to the turn of the new millenia. I quite like Napa and Sonoma. They often remind me of the Italian countryside. It also costs a third of the traditional costs to go to Italy. Food isn't quite up to par, but it's a wonderful experience. Especially during the fall and winter. The grape vines may be barren, but it's not wedding season and no one will see a Bride-zilla around. The restaurants and wineries also offer unique North European style fare. Very rich, very filling. One place managed to work cream into every dish. You won't realize it, even with an astute palette, but it's there.
Had wonderful piroshki (sp?) in Russia. Beef, beef and potato, potato, mushrooms and spinach, garlic and sardines (amazing), and more. Had pierogies and other typical Polish fare in Poland. I recall tears streaming down one of my eyes after consuming a large chunk of their rokpol, a Danish blue type of cheese. It was akin to licking a car battery; a true zing was had in the old cranium.
In regard to the sandwich again, I used to lightly fry my tomatoes with dried rosemary but found it imparted a strange flavor. I may make a rosemary mayo on the fly using fresh rosemary from the garden provided it's not a pain to wash, but the rosemary in the bread works fine. Bonus if you use a cheese in the bread making process, so when you toast it, you get a wonderful crisped cheese flavor and aroma. The caramelization adds a subtle layer of flavor.
I often wonder how I've managed to keep fit my entire life given my love for food and drink.
