In a small saucepan, add chicken breasts and 3 cups of water. Bring to a boil, and boil for 10 minutes. Once done, set the chicken aside to cool.
In a large pot or dutch oven, heat avocado oil over medium heat. Add the onion, bell pepper and zucchini, and cook for 4 minutes. Add the garlic, and cook for an additional minute.
Season veggies with chili powder, cumin, paprika, salt and pepper. Cook for an additional minute.
Add the diced tomatoes, beans, corn and chicken broth.
Bring to a gentle boil.
Using two forks, shred the chicken breasts thoroughly, and add them to the chili. Mix to combine, reduce heat to low, and let simmer for 20 minutes.
Before serving, add chopped cilantro and stir.
