This pesto is not only the best pesto I've ever made, it's the best pesto I've ever tasted, period. If you have cleavers, please try this pesto now. If you trust no other recipe on this site, trust this one. This garlicky cleavers pesto is something you need in your life.
This pesto is fast, simple and can go on absolutely ANYTHING, but of course, I enjoy it best simply tossed with some pasta. This wild herb pesto is a great condiment, it's super healthy because of the nutritious cleavers, and low-carb keto, as well as being vegetarian. If you omit the cheese, it's also Paleo and Vegan!
Cleavers are a very common backyard "weed" that's super easy to identify. If it's early to mid-spring, I guarantee that you can find some near you, perhaps in a local park. They have a great herbal flavor, vaguely like oregano, but mostly uniquely their own. Cleavers should be boiled before eating, and I prefer them pureed as well, to avoid textural issues.
