Easiest thing you can possibly cook, PD. Even if it's a little expensive, look for it on sale and you can throw it in the freezer.
One of the flavors they use at Joes Crab Shack is really just rotisserie seasoning.

So when we're lazy, we just boil water, throw that in and throw in the crab for a few minutes. We eat like kings in our own house with minimal effort.
