Prep time: 15 minutes. Cook time: approximately 35 minutes, with additional roasting if larger beet cubes require more time. Total time: approximately 50 minutes. Yield: 4 generous main-dish portions or 6 smaller side-dish servings. Oven temperature: 400°F (200°C). Nutrition estimates assume 6 side-dish servings made with butternut squash, goat cheese, walnuts, honey, and the full amount of olive oil and dressing. Roasted vegetable ingredients: 2 cups butternut squash peeled, seeded, and cut into 3/4-inch cubes, 2 medium beets peeled and cubed, 2 medium zucchini sliced into 1/2-inch half-moons, 3 tablespoons olive oil divided, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1/2 cup walnuts or pecan halves. Salad ingredients: 1/2 cup crumbled goat cheese, 1/2 cup fresh pomegranate seeds, 3 cups arugula or baby spinach, and 1/4 small thinly sliced red onion. Dressing ingredients: 3 tablespoons olive oil, 1 tablespoon balsamic vinegar, 1 tablespoon honey or maple syrup, 1 teaspoon Dijon mustard, 1 tablespoon fresh lemon juice, 1/4 teaspoon salt, and 1/8 teaspoon black pepper. Preheat oven to 400°F (200°C) and line two baking sheets with temperature-rated parchment paper or lightly grease them. Cut butternut squash and beets into 3/4-inch cubes and zucchini into 1/2-inch half-moons. Toss squash and beets separately with 2 tablespoons divided olive oil and most of the seasoning. Spread in single layers on separate baking sheets and roast for approximately 20 minutes. Toss zucchini with the remaining 1 tablespoon olive oil and reserved seasoning. Turn the roasted vegetables, add zucchini to a sheet with sufficient room, and roast for another 15 minutes until vegetables become fork-tender and lightly golden. Beets may require additional roasting depending on size. Toast walnuts or pecans on a separate tray during the final 5 minutes, watching carefully to avoid burning. Whisk dressing ingredients until combined. Arrange fresh greens on a large serving platter, add slightly cooled roasted vegetables and thinly sliced red onion, then sprinkle with crumbled goat cheese, pomegranate seeds, and toasted walnuts or pecans. Drizzle dressing immediately before serving. Serve warm or at room temperature. For the best appearance, roast beets separately to prevent staining and avoid overcrowding the baking sheets. Add zucchini near the end to maintain texture. Optional variations include sweet potato instead of squash, feta instead of goat cheese, pecans instead of walnuts, baby spinach instead of arugula, or maple syrup instead of honey. Cooked quinoa, chickpeas, or lentils can make the dish more substantial. These variations are not included in nutrition estimates. Prepare roasted vegetables and dressing up to 2 days ahead and refrigerate separately. Store roasted vegetables in airtight containers at 40°F (4°C) or colder for 3 to 4 days. Fully dressed salad tastes best within one day. Freezing the fully assembled salad is not recommended. Nutrition values are approximate per serving based on 6 servings and vary by vegetable sizes, cheese type, nut choice, dressing consumption, and portion size.
