I enjoy cooking. My favorite dishes were always those that used chicken, but now I have many vegetarian friends so I had to learn how to make more things with vegetables. Right now I use a lot more celery. I learn to use it in almost everything, even fried celery! What I don't like is to do the dishes. When I invite friends to eat, I cook, but they are the ones that clean everything.
