Roughly chop your onion, carrot and peppers. Add them to a food processor and blend until they are a veggie paste consistency.
In a large pot or dutch oven over medium heat, add some oil. Once hot, add the vegan meat. Break up your meat and cook until browned, about 5 minutes. Then add in your veggie puree. Stir to combine.
Add the chili powder, cumin, smoked paprika, and stir to combine, then add in the minced garlic. Stir to combine and cook for a minute.
Add in the vinegar and 2 cups of the broth and stir. Next add in the Masa Harina and stir to combine.
Lower heat and simmer for about 10 minutes or until reduced to desired consistency.
Taste and adjust for seasoning, add more masa harina if you think the chili is too thin. Likewise, add more broth if it's too thick.
Once chili is where you like it, cover and keep warm on low.
