These days there are actually a ton of really good ciders (which are naturally GF). There are a number of GF beers, but they're mostly not that good.

I can also recommend Udi's GF bread, a bit pricy and you keep it frozen, but it defrosts in the toaster easily and is actually pretty decent.

I'm afraid you're out of luck for GF Pizza, of most of the frozen ones the cardboard packaging tastes better.
