Heat a large saucepan or stockpot over medium heat. Add ground sirloin, water, and onion; cook and stir until onion softens, about 3 minutes. Season with salt and pepper. Continue cooking until beef is halfway browned, 2 to 3 minutes. Add cubed sirloin and garlic. Cook, stirring often, until onions are translucent but not browned, 3 to 5 minutes more.

Add diced tomatoes, kidney beans, tomato paste, green chiles, chili powder, cilantro, cumin, ginger, curry powder, and cayenne pepper to the pan. Bring to a boil, cover, and reduce heat to low. Simmer, stirring occasionally, about 30 minutes. Season with salt and pepper and simmer until flavors blend, at least 2 hours.
