In a large skillet or wok, combine the onion, 2 tablespoons of the broth or water, thyme and pepper flakes, and cook over medium-high heat for 10 minutes, or until onion is tender and just begins to brown, stirring occasionally. Add the remaining broth or water, the squash and barley; cover and cook for about 5 minutes, or until squash is tender-crisp. Add remaining ingredients, and stir thoroughly to combine. Serve, or re-cover and refrigerate. Bring almost to room temperature before serving.
NOTE: Patty pan, also known as white bush or scallop squash, also can be used.
