Thanksgiving Update: Tofurkey!

There may not be turkeys in space, but what holiday feast would be complete without a large, gross yellow bird substitute?

This PR adds two new recipes for the chef to cook:

Stuffing: 1 bread, 1 salt, 1 pepper, 5 water
Tofurkey: 2 tofu, 1 stuffing

Paradoxically, the Tofurkey contains trace amounts of sleep toxin and will put you to sleep if you eat too much.
