I can only describe this salad as an amalgamation of colors and flavors that I love, with a hit of za'atar that keeps everything together. It's a perfect summer salad. Use ripe and juicy cherry tomatoes, preferably as red as you can get them, and let the butter beans and pickled red onions bring the whole salad up another level. Parsley is there for some *greenage* but I wouldn't be mad at you if you also wanted to throw a little lettuce in the mix!
