Tough, flavorless beef. What to do?
I'm on vacation and in a foreign kitchen. Some friends presented me with a generous, albeit unfortunately tough and flavorless gift. I've got big chunks of red beef (don't know what part of the animal it came from). In my hotel/apartment, there's no oven, food processor nor a good knife. I've basically have a stove, a pot and a microwave oven. What can I do? Please help me.
