This is a summer staple that is excellent on tomatoes, grilled vegetables, boiled or roasted potatoes, and fish, chicken, or beef. You can also use it to add flavor to a pasta salad, sandwiches, and summery crostini.
Put all of the ingredients into a blender and run until smooth, stopping to scrape down the sides and run again, as needed.
Transfer to a jar or bowl and store in the fridge, where it will keep for up to 5 days.
