Finely dice the yellow onion and red bell pepper, and mince the garlic clove.
Heat the olive oil in a medium pot over medium-high heat until shimmering.
Add the ground chicken to the pot, breaking it up with a wooden spoon, and cook until browned and no longer pink.
Stir in the diced onion and bell pepper, sautéing for 3-4 minutes until the vegetables begin to soften.
Add the minced garlic, chili powder, cumin, sea salt, and black pepper, stirring for 1 minute until the spices are fragrant.
Pour in the tomato puree, black beans (rinsed and drained), and water.
Bring the mixture to a gentle boil, then reduce the heat to low and cover.
Simmer for 15 minutes to allow the flavors to meld and the sauce to thicken slightly.
Remove from heat and serve hot in a deep bowl.
