3 acorn squash, cut in half and seeds removed
3 T. extra virgin olive oil, divided
3-4 cloves garlic, finely minced
4 oz. pancetta, diced
1½ lbs. Portobello mushrooms, roughly chopped
½ medium yellow onion, thinly sliced
1 c. green lentils, cooked
1 1/2 T. fresh sage, finely chopped
¼ c. dry red wine
1/3 c. dates, roughly chopped
¼ c. walnuts, chopped
¼ c. Parmesan cheese, freshly grated
Sea salt and pepper to taste

Also, need:
Non-stick cooking spray


  1. Position oven rack to center position, then preheat oven to 400°F. Spray a large baking dish with non-stick cooking spray and set aside.
  2. Place the acorn squash halves cut side up in the prepared baking dish and brush the cut edges with one tablespoon of olive oil. Season with salt and black pepper, to taste. Place baking dish on center rack in preheated oven and roast for 40 minutes, or until the squash is fork tender.
  3. In the meantime, heat the remaining olive oil in a large skillet over medium heat. Add minced garlic and pancetta and cook, stirring occasionally, until slightly browned, approximately 2-3 minutes.
  4. Add chopped mushrooms and cook, stirring occasionally, until they start to brown, approximately 4-5 minutes. Add sliced onions and continue cooking, going once or twice, for another 3-4 minutes.
  5. Stir green lentils, fresh sage, and red wine into the skillet. Cook, stirring occasionally, until mixture thickens, approximately 8-10 minutes. Remove from heat and stir in the chopped dates and toasted walnuts. Season with salt and black pepper, to taste. Set aside.
  6. When ready, remove the cooked squash from the oven and cool slightly before filling each half with the Portobello mushroom mixture. Sprinkle each half with some freshly grated Parmesan cheese.
  7. Return stuffed squash to oven for another 5-10 minutes, or until heated through and the cheese melts. Remove from oven and serve immediately. Enjoy!
