Very good bread made with basic ingredients and a simple recipe. The ingredients cost about $2-4 with organic flour to make 3 loaves, which is still about 3 times cheaper than buying it in the store. And I like it much better than any bread I can find in any store or market (but maybe only because it's fresh).
Baking bread is especially efficient in the winter, where the heat from the oven isn't wasted.
It's not hard to make bread either, and slightly fun. I don't recommend a bread maker, because most people's I've heard from wrecks the bread about half the time. You only have to knead it for about 5-10 minutes anyway, which I don't consider much effort.
