I know. I know. It’s hard to resist serving tomatoes with fresh mozzarella, balsamic and basil in the summer. I’m with you but you must fit Tomato, Onion, and Oregano Salad into the rotation. My mom used to make this salad for us all of the time in the summer. I only slightly tweaked her recipe (because it doesn’t really need tweaking!) by using fresh oregano leaves in addition to dried oregano. As you’ll see below, this salad is so easy to make, it really doesn’t require a formal recipe.
