Preheat oven to 450º F.
Peel and chop butternut squash in dice sized cubes. Drizzle or spray the squash with half of the olive oil, and roast the squash for 30 minutes.
In a large dutch oven or soup pot, add the remaining 1 tablespoon of the olive oil and the onions. Saute on medium heat for about 7 minutes, until onions are softened.
Add the turkey, spices, and salt to the onions, and stir to break up the turkey as it browns. Saute for about 10 minutes.
Add the diced tomatoes, tomato paste, and vegetable or chicken broth. Stir the mixture together, and bring to a simmer. Reduce the heat, and continue to simmer, stirring occasionally, for 30 minutes.
Adjust the seasonings by adding more chili powder or cayenne pepper to add spice, or adding more sea salt, if necessary.
Add the roasted butternut squash and zucchini to the chili, and simmer an additional 5 minutes.
Serve garnished with favorite toppings.
Store chili for up to 3 days in the refrigerator, or up to 3 months packed in air tight containers in the freezer.
