Cook lentils, split peas, or beans according to the package.
Cook an onion, 4 sticks of celery in a frying pan or wok. Bok choy too...
Heat up a box of vegetable broth (low salt) and about equal part of water.
Add about 4 carrots, 1 large potato (cut in 1" cubes), and lentils/peas/beans. Even frozen peas or a can of beans will work... but better and cheaper to make from scratch.
If your wife isn't looking, add other stuff that you like (like kale) and she doesn't. Chop it up small so she doesn't catch you.
Put in the cooked onion and celery.
Add a heaping teaspoon of salt, tablespoon of parsley, bay leafs (2), and heaping teaspoon of herbs de Provence.
Simmer until potato is soft.
You can blend some of the soup... but I like it as it is. It is almost a stew sometimes... or you can add water. Hot sauce is good too.
I guess you could add garlic, but since I don't like garlic I'm not going to tell you that.
You now have food for about 4 or 5 days.
