Korean food is always accompanied by a plethora of small bowls of various salads, pickles, and kimchee (actually I think they're all generically callled Kimchee, but you would always be served with several types). That is where the "pickles" come from. Have patience, I'm sure someone will come in with some good recipes.
I like to take soy sauce, hot peppers, maybe a little vinegar, a dab of sugar, chopped scallions. Marinade beef ribs or thin sliced beef for a few hours, then grill over charcoal. Ribs are kal bi, thin sliced beef is bulgogi. Since I don't use an exact recipe, someone will chime in with one. Some recipes call for rubbing the thin sliced beef with sugar first. Be careful. It makes for a tender peice of meat, but beware. Like with yogurt in Indian foods, pure sugar can literally turn your meat to mush after a few hours.
Another favortie is chop chae. Soak bean thread noodles according to package directions. Meanwhile chop spinach and scallions. Other appropriate vegetables are bean sprouts, grated carrots, or shredded squash. Quite often this is made with leftover bulgogi, but if not, every time I've had it, it had some thin sliced, marinated beef in it. Toss in the skillet or wok and keep tossing until all is coated. Add a little soy/sugar/garlic/hot pepper mixture towards the end. Yummyummm.
Many Korean recipes reflect the turbulent relationship between Japan and Korea.
If you want exact recipes for any of these, respond and I'll go get my trusty Korean cookbook, or better yet, email a friend for it.
