Nice one Mary Beth! Lambsquarter is the best! So happy you found it out :)
We have been harvesting the lambsquarter so much this summer. It's for sure one of my favourits. Almost unbelievable how abundant it is and how nutritious. I like to call it "wild spinach" to make it sound better and more appealing to folks who never heard about eating it before. Way better of going out to the garden for some of this stuff then going to the super market and paying an arm and a leg for some sub par spinach. They taste very similar in my opinion.
We have been making some super tasty recipes with it, like a spanica pita type thing, omelettes, quiches, etc. If anyone is interested we are having a little online wild food cooking class where we go over a bunch of recipes using wild plants and lambsquarter is on the menu. It's a lot of fun. The link is in my signature.
I like to harvest as much as possible when it's young and growing really well, then dry it and store it for the winter months to be used as a "superfood" powder in smoothings, soups and what not.
