Or just potato and white bean, since I bought a lot of the former at Monday's farmer's market (I always buy more potatoes than I need. Always.). And I had to resort to jarred pesto, since I didn't have everything required to make one from sage and walnuts (which sounds good, but at what point do you have to stop calling it pesto?).
This was one of the best returns on investment I've had in a while. The leeks take long enough to cook that you can do everything else at a rather leisurely pace in the meantime, instead of having everything ready to go before you get started, but the entire recipe can be ready in a half hour or so. And of course, pesto can make almost anything taste good. Together with what was left of the bread from Monday, this made a very satisfying meal for a weeknight.
L ate half the beans out of the colander before I could put them in. She's got the first cold of the school year now. I am still obsessing over that rehab in Maynard, and counting down the days before our big October deadline at work.
