Start by chopping your chicken breasts into bite-sized cubes so every spoonful gets a good piece of protein. Dice your onion, bell pepper, and jalapeño, then mince the garlic. Having everything prepped ahead of time makes the next step go much faster.
Add the chicken, black beans, corn, crushed tomatoes, chipotle peppers, jalapeño, onion, garlic, bell pepper, chicken broth, tomato paste, salt, pepper, chili powder, and paprika into the slow cooker. Give it all a good stir so the spices coat everything evenly before you close the lid.
Cover the slow cooker and cook on low for 5 to 6 hours, or on high for 3 to 4 hours. I usually go with the low setting on busy days since it lets the chicken get incredibly tender while I'm off doing other things.
Once the cook time is up, stir in your diced avocado right before serving. I like to add it at the very end so it stays creamy instead of turning mushy from the heat.
Ladle the chili into bowls while it's still hot and add any toppings you love. This is the part where I usually reach for tortilla strips and a big spoonful of sour cream
