The art to a composed salad is layering, seasoning, enhancing flavors and incorporating many textures and temperatures. I love the way Zucchini can look like gorgeous soft ribbons when then have been salted for a short time... 
Then to add some color and texture, cubed Avocado and quick-pickled red onion....
For more flavor, texture and color : sliced heirloom cherry tomatoes of all colors and shapes. And a gorgeously chewy and herb packed farro salad...
Keep the layers coming with a finessed sprinkle of fresh micro cilantro, micro arugula, regular cilantro, edible marigolds, dry roasted sliced almonds, fried capers, mint, parsley, and a touch of crispy breadcrumbs....
Summer produce looks best when it looks as if it is literally springing out the earth on the plate.
