Take some radish greens, carrot greens, parsley, and mustard greens, and chop them up and mix them. Add a couple cloves of garlic and a big handful of pumpkin seeds and/or pine nuts (I like a mixture of the two). Cover the whole shebang with a generous helping of olive oil and purée.
Thinly slice the radishes and the carrots from which you rescued the greens, and use them as excuses to scoop heaping gobs of pesto down your throat.
