There are all kinds of Pistou. This one is sort of Provencal. That way, we don't actually have to call it French. We can think of it as "late Roman".
What Goes In It:
Pistou (you can get prepared Pesto, if you would rather).
4 cups of clear stock (veggie or chicken) It needs to be as clear as you can make it, so if you are making it yourself, strain it, strain it, strain it!!!
one medium potato: diced
pasta: small stuff, not big stuff...a quarter of a cup
some canned cannellini beans: drain them and soak them to leech the the salt out
salt to taste
pepper to taste
Other Stuff:
one red onion: in thin wedges (or leek slices or chives)
a few baby carrots: cut into disks or strips (you could do some parsnips, too)
