Prepare the vegetables by chopping and dicing ahead of time.
Then set aside. In a large dutch oven or stock pot, pour in the butternut squash, sweet potato, garbanzo beans, onions, and garlic.
Add the tomato sauce and diced tomatoes, stir to combine.
Bring the chili to a medium low heat, then add in the pumpkin purée and seasonings, then stir using a wooden spoon to combine. Cover and let simmer on a low flame for 2-3 hours, until the squash is tender.
Notes
Chop all the vegetables in advance, that way you can just throw it all into one large pot at once rather than stopping and chopping vegetable by vegetable.Cook low and slow on the stovetop, or set the crockpot for a low heat. We don't want any burning!If you want your chili on the thicker side, keep the ingredients as is, but if you want it a little thinner, add in ½ cup of water or broth.
