Great suggestions, thanks! This thread is making me hungry. Or maybe that's the effect of the 15 mile ride I just finished. I like the idea of using little squirt bottles and spray bottles for oil & liquids, maybe soy sauce in one.

Oh yeah, I forgot tuna comes in pouches these days. And sardines are single serving.

My husband pointed out that many groceries have a butcher section, maybe they'd be able to sell me smaller quantities.
