For a deeper flavor, try roasting the vegetables instead of sautéing them. Toss them with olive oil, herbs, and seasoning, then roast at 400°F (200°C) for 20-25 minutes, or until tender and slightly caramelized. Consider adding a splash of balsamic vinegar or lemon juice at the end for a bright, acidic finish. Cherry tomatoes, zucchini, or eggplant would be delicious additions to this vegetable medley. Feel free to experiment with your favorite seasonal produce.
