Optional: chopped cilantro to stir into chili after it is done cooking. I went without the cilantro
Instructions
Heat olive oil over medium-high heat. Add onion and potato and cook, stirring often, until the onion is slightly softened, about 4 minutes.
Add garlic, chili powder, cumin, chipotle and salt and cook, stirring constantly, until fragrant, about 30 seconds.
Add water, bring to a simmer, cover, reduce heat to maintain a gentle simmer and cook until the potato is tender, 10 to 12 minutes.
Add beans, tomatoes and lime juice; increase heat to high and return to a simmer, stirring often. Reduce heat to maintain a simmer and cook until slightly reduced, about 4 minutes.
Remove from the heat and stir in cilantro, if using.
