Season the beef cubes evenly with kosher salt and black pepper.

In a large skillet, heat the olive oil over high heat. Add the seasoned beef in batches and cook for about 2-3 minutes on each side until browned.

Reduce the heat to medium-high, then add the diced onions and jalapeños to the skillet and stir occasionally for about 5 minutes until they are slightly softened.

Add the minced garlic and let it cook for an additional minute to blend the aromatic flavors.

Stir in the chili powder, ground cumin, diced tomatoes (with their juice), black beans, kidney beans, chopped green chiles, and beef broth. Ensure everything is well combined.

Lower the heat and let it simmer for 30 minutes to an hour, stirring occasionally until the meat is tender and flavors meld beautifully.
