I saw a fun post in Pregnancy on food cravings -- youngartista said she was craving jelly beans (Wal-mart was out!), and she asked other moms what they currently had a hankering for.
If you're dying for quick fix of chocolate, try Cafe Kim's recipe for Chocolate Brownie in a Mug. That sucker only takes two minutes to cook, so it is pretty much instant gratification.
What are you craving right now?
