Heat a large pot over medium heat.
Add the fat to the pan and swirl it around. Add the peppers, carrots, onions, garlic, and cumin to the pan with a bit of salt and pepper. Stir to coat with the fat and cook until aromatic and the onions become a bit translucent, about 5 to 7 minutes. Stir occasionally.
Add the ground beef to the pan. Stir and break up the meat. Add a bit of salt and pepper, continuing to stir and breaking up the meat.
Add the tomato paste and raisins. Stir into the mixture, then turn the heat to low.
Allow the mixture to simmer and cook for about 30 more minutes, stirring occasionally.
Taste, adjust the seasoning with a bit more salt and pepper, if it needs it, then serve!
