Thinly sliced meats are ideal for hot pot since they cook quickly and are easy to pick up with a pair of chopsticks. Look for pre-sliced shabu-shabu meats at Asian grocery stores, usually in the frozen section of the meat department. Any type of meat can be used — the sky is the limit. Beef, chicken, pork, or lamb, it's up to you. You can also use seafood if you like — popular choices include shrimp, squid, fish fillets (cut up), and fish balls. Tofu is also a must; just be sure to purchase firm tofu so that it doesn't fall apart as it simmers.
