Look, even if you're not a slow cooker believer, you will be after trying this chili. It's a set-it-and-forget-it kind of recipe involving only a handful of ingredients. I added pureed pumpkin to this recipe after having great success with this vegan pumpkin chili, and I highly recommend it. The pumpkin thickens the chili and gives it an even creamier, richer consistency. Also, if you're afraid that the beans won't cook after the allotted time — don't be! They maintain their shape yet are perfectly cooked though.
