What's your most used "weed" in the kitchen?

We have Lambsquarter and Nettle popping up around us this time of year. Theres alot of other stuff to forage this time of year but those two make up about 30% of our diet when they are out and about. If harvested right there season can be from spring to the hard frost. The neighbor used to think I was crazy but I shared some Lambsquarter and she's starting to get why I keep a patch in the garden as its way more sturdy then spinach and I think it taste better. What weeds seem to find there way onto your plate?

Lambsquarter hits every salad.  While it grows wild, we also raise it in a container on our back deck.

Definitely nettles. Any time you think you're eating spinach at my house.. it's probably not spinach!

Nutritious, tasty and free, comes up year after year in my patch.

Dandelions also feature regularly, and both get used in my herbal teas as well as cooking.
