Heat the olive oil in a medium pot over medium-high heat.
Add the ground chicken to the pot, breaking it into small crumbles with a wooden spoon until browned and fully cooked.
Stir in the diced yellow onion and red bell pepper, sautéing for about 4 minutes until the vegetables are tender.
Add the minced garlic, chili powder, and cumin, stirring constantly for 1 minute until the spices are fragrant.
Pour in the tomato puree, rinsed black beans, and water, then stir to combine.
Season the mixture with sea salt and black pepper.
Reduce the heat to low, cover the pot, and simmer for 15 minutes to allow the flavors to deepen.
Ladle the chili into a bowl and serve warm.
