My standard salad is romaine lettuce, cucumber, red bell or capie pepper, sliced mushroom, a small amount of minced red onion, grated carrot, and if I have it on hand, some shredded fresh basil (dried basil can be nice too but it's a very different flavor). Add olive oil and some black pepper and mix it up, then let it sit for five minutes or so so the onion flavor sinks through. Then add some balsamic vinegar and enjoy - and toast up a little bread on the side to make it more filling and soak up the last of the dressing. I've never been a fan of croutons, but a little bread can take a nice big salad and turn it into a meal. I also recommend adding some cheese, but it has to be a good kind of cheese to match the flavors. Mild cheddar can work nicely, or goat cheese if you like that. In Prague they have "Balkan cheese" which I *think* is a type of goat cheese, but quite salty, and you can buy it flavored with things like red peppers and garlic. Mmmmmmmm.
By the way, friends, I've been deported from Prague and am hanging out in Scotland until they let me go back (up to 3 months). Any advice on food here? There is certainly a lot of fried, um, everything. Anything else I should watch for and enjoy? I have access to quite a nice kitchen at my friend's apartment where I'm staying, so I can cook. What can I get here that I won't be able to get when I get back home?
