Kori's Tips
For more helpful hints, substitution ideas, cooking tips, and other delicious recipes check out my post above.TIPS: Roast the pumpkin slices, cook the barley, and make the dressing up to several days in advance for quick assembly.VARIATIONS: Use feta or blue cheese instead of goat cheese. Swap the spinach for baby greens or romaine. Farro or quinoa can stand in for the barley.MAKE IT FLEX: Serve it with roast chicken, pork tenderloin, or baked salmon, or alongside the Thanksgiving turkey.SERVING SUGGESTIONS: Serve on a platter, in a large bowl, or on individual plates. Toss it with my Maple Balsamic Dressing, pair it with a bowl of soup for a cozy fall meal, or bring it as a holiday side.
