For some it may be easy to avoid, but most of what we cook is done in cast iron. We have 3 stainless cooking pots, but now that the wood stove is going we have been doing more and more with cast iron, since we don't like to use SS on the wood stove, and it seems silly to use the hot plate when the wood stove is going already. The dutch oven was a recent acquisition, but we have cast iron skillets and a griddle... last winter we didn't cook much for us, and didn't for the birds at all since we didn't have running water. But we have water now(sorta, at least we have way more water access than last year!) and have moved the birds off the mostly seed diet we had to have them on last year.
As for the oven? We don't even have one here. We season our cast iron on the stove and below the smoke point of the oil we use. I guess I could cook rice (and everything else) for the birds in the microwave, but I don't really like to use that thing too much when avoidable.
