To make this with roasted butternut squash instead of canned get one 2-3 lb butternut squash. Preheat oven to 400 Deg F. Cut squash in half, remove seeds then brush with olive oil, season with salt and pepper. Place on roasting pan or baking sheet with cut side facing up, and roast for 30 minutes until very soft. Let cool for 20 minutes, scoop out roasted squash and puree for a smoother texture. Reserve one and one half cups for the hummus, save the rest for another use. Can be frozen up to three months.
