Place all of the pesto ingredients in a blender or food processor and whiz up until you have a green, bubbly sauce, adding a splash of water if the pesto is a little thick. Taste, season, and adjust anything that needs adjusting.
In a large saucepan, heat the olive oil and soften the onion. Add the zucchini, then pour in the stock and simmer on low for 8 to 10 minutes. Add the peas and arugula, bring back to a boil, and cook for another 3 or 4 minutes until the vegetables are tender.
Let the soup cool for 15 minutes or so and then, in careful batches, mix in a blender until you have a velvety purée. Reheat in the saucepan or serve cold, as it works either way. You can either run 4 tablespoons of pesto through the soup when you’re serving or reheating, if you are. Or, if serving cold, add it to the blender when you are puréeing the batches.
Nutritional information includes 1/2 cup of basil, 2 tablespoons of pine nuts, 1/8 teaspoon of added salt per serving, 1/2 cup of arugula, and using half of the pesto.
