Parsley Pesto
1 cup parsley leaves (thin stems are okay), rinsed and dried
salt
1/2 clove garlic
1/4 cup sunflower or extra-virgin olive oil, or more
1 tsp apple cider vinegar or freshly squeezed lemon juice
Combine the parsley with a pinch of salt, the garlic, and about 1/2 the oil in a mini-food processor, stopping to scrape down the sides of the container if necessary, and adding the rest of the oil gradually. Add the vinegar, then a little more oil or some water if you prefer a thinner mixture. Taste and adjust the seasoning, then serve or cover and refrigerate for up to 2 days.
