Chives! These are the most OMG plant in my garden right now. First of all, they are low maintenance in being perennials. Second, I've never found a weed around them. Third, and not in order of actual importance, there are reports now of fantastic health benefits from Chives.
Chive Pesto is my new favourite pesto. I am actually mad about pesto from basil, cilantro, pea shoot, arugula, etc. Chive is now on the top of the list.
1 cup roughly chopped chives
1/2 cup ground almonds
1/2 cup grated parmesan reggiano or padano
1/4 tsp ground black pepper
1/4 + cup good olive oil
pinch salt, to taste
Grind up all ingredients to a paste. Enjoy as a pesto, as an ingredient, as a sandwich spread, etc. In pasta, try with chopped tomatoes to bring out the sweetness of the chives.
