Chicago artist and permaculturalist Nancy Klehm gave me this idea. Funny how it takes an out of town visitor to make you aware of a resource at your own home–right now our yard is choked with nasturtium and I’ve never made good use of the leaves. I have used the flowers for a pesto, but it’s kinda labor intensive. Nancy made a pesto with the leaves and I had to try my own version:
Nasturtium leaf pesto
2 fistfuls of nasturtium leaves
1 fistful of nuts–pistachios preferred but any will do
a half fistful of grated Parmigiano-Reggiano
Roast nuts in a pan. Let them cool and add to a food processor with the nasturtium leaves, cheese, salt and pepper. Add olive oil as you pulse the processor. Process until smooth. Add to your favorite pasta or use as a dip. Garnish with a nasturtium flower.
