1cupthinly sliced summer squash(green or yellow or a combination; if your squash is more than 1 1/2 inches in diameter, halve it lengthwise before slicing)
In a large bowl, combine the farro (or barley), grape tomatoes, summer squash, and arugula.
In a small bowl, combine the scallions, rice vinegar, olive oil, salt, and pepper.
Pour the dressing over the salad, add the basil leaves, and gently toss until everything is well combined. Serve cool or at room temperature.
Notes
I also used green and yellow pattypan squash in this recipe because that’s what I had on hand, but you can use any small, firm summer squash or zucchini. Sometimes, people don’t realize you can eat summer squash uncooked, but it’s great to use raw in salads and other recipes. Make sure it's not too mature or large, as then it might have a slightly mealy or watery texture.
You can also sub in diced tomatoes for the smaller cherry or grape tomatoes. Try other fresh herbs in place of the basil.
Try spinach instead of the arugula if you like a milder flavor.
