3 tablespoons butter
2 medium yellow onions, finely chopped
3 garlic cloves, minced
3/4 teaspoon salt
1 tablespoon chopped fresh sage
1/3 cup chopped walnuts
1/3 cup chopped pistachios
1/3 cup chopped almonds
1/3 cup chopped pine nuts
1/3 cup plain low-fat yogurt
2 eggs, lightly beaten
About 1/2 cup freshly shredded parmesan cheese
2 delicata squash (about 2 pounds total), halved lengthwise and seeded
Preheat oven to 350°. Melt butter in a large frying pan over medium-high heat. Add onions, garlic, and salt. Cook, stirring occasionally, until onions are soft, about 3 minutes. Stir in sage and cook until fragrant, about 1 minute. Stir in nuts. Set aside.
In a large bowl, combine yogurt, eggs, and 1/2 cup parmesan. Stir in nut mixture. Divide stuffing among squash halves, sprinkle with more parmesan, and bake until tender when pierced with a fork and tops are browning, about 45 minutes.
