Minecraft wiki entry for Beginner%27s_guide, associated text: Once you have tools and shelter, your next priority is food. Hunger takes a while to hit, so it shouldn't be a problem on your first day, but you should try to pick up some food for when it does, just so you don't get into an emergency situation. Just killing a few animals and cooking their meat will certainly tide you over for long enough to make more permanent arrangements. The occasional apple or sweet berries can help a bit, but mind those damage-dealing bushes!
