Preheat the oven to 400 degrees. Wash the outside of the squash and place on a cutting board. Use a sharp knife to cut the squash in half. Scoop out the seeds (you could reserve and roast but I didn’t for this recipe) and as much stringy flesh as you can and set aside. Drizzle the inside with 1 tbsp of olive oil and using your hands spread it all over the inside and outside. Sprinkle sea salt and cracked pepper. Place on a baking sheet cut side up for 45-50 minutes or until easily pierced with a fork.
Rinse quinoa in a fine mesh sieve until water runs clear. Place in a small pot and add 1 3/4 cup water and a pinch of sea salt. Bring to a boil and then cover for 15 minutes on low heat. Remove from heat and let quinoa rest for an additional 10 minutes with lid on before fluffing with a fork.
While quinoa is cooking, preheat the oven to 400 (you can cook your tofu at the same time as your squash!). Press any extra liquid out of tofu and pat dry. Cut into small cubes and toss into a bowl. Drizzle with 1 tbsp olive oil and sprinkle with sea salt and cracked pepper. Place on a parchment lined baking sheet and roast for 20 minutes. Tofu should be crispy on one side but still soft and tender.
Heat 1 tbsp olive oil in a pan and add chili flakes and garlic. Saute until fragrant. Add portobello mushroom and cook until mushrooms start to soften and release water. Place cooked quinoa, cooked mushrooms, cherry tomatoes, chopped spinach, most of the pomegranate seeds and chopped cilantro into a bowl and gently toss to combine. Season with salt and pepper.
Spoon quinoa mixture into the bowl of the cooked acorn squash. and place back into the oven for 8-10 minutes. You will have PLENTY of filling leftover. Serve on the side of your squash or save for leftovers.
While squash and stuffing are baking, make tahini sauce. In a small bowl add a heaping tbsp tahini, 1/2 lemon juiced, 1 tbsp maple syrup. 1 clove minced garlic. Stir to combine. Add warm water to thin. Start with 2 tbsp and keep adding until you reach your desired consistency. Don’t add too much water or your sauce will be too runny. Season with salt and pepper.
Remove squash from the oven and drizzle with tahini sauce.
