I'm a big fan of seafood. Although pricey at restaurants, it's fairly cheap and extremely easy to cook it at home if you buy on sale. Cooking it yourself provides enough seafood for two people for around $20. I keep an eye out for sales on snow crab and stock up when it's about $6.99 a lb or less. When I buy it I ask if they have any still frozen because I have no idea how long it has been thawing out in the display case and I don't want crab that's be frozen, thawed, frozen again for storage, and then thawed again for use. I also went with some head-on shrimp that was only $3.99 a lb to save a bit of money. Although you're throwing away some of the weight because of the discarded heads, it comes out to about $5.95/lb, which is still pretty cheap.
