FWIW, I looove a lot of offal and have various recipes (including some without onions or garlic).

It's not the first thing I'd recommend reintroducing, because most offal is pretty rich and that can be hard to digest when you're recovering from any kind of stomach illness -- if eggs are still making you nauseous, liver certainly will.

But if you get to the point where you want to try offal, I'd be happy to have my brain picked.
