Preheat a large pot over medium-high heat. Add in the olive oil and ground beef.
Using a wooden spatula, break up the ground beef as it cooks. Cook until beef is no longer pink, about 5 minutes.
Add in the onion, poblano pepper, jalapeno pepper, and bell pepper. Sautee for 5 minutes or until the onion becomes translucent. Add in the garlic and sautee an additional 30 seconds.
Add the remaining ingredients. Stir to combine. Cover, bring to a boil, and reduce to a simmer. Simmer for 10-15 minutes.
Adjust seasoning according to taste. If the liquid has evaporated too much during cooking, add a splash of beef stock until desired consistency is reached.
Serve warm with toppings of choice (chips, cheese, cilantro, sour cream, and/or lime wedges!)
