Heat the oil in a skillet over medium. Add the onion and pepper and cook until they begin to soften. About 3-4 minutes
Add the ground beef and continue to cook on medium until it's mostly crumbled and cooked through.
Sprinkle the taco dust seasoning and mix thoroughly with the ground meat.
Add the tomato paste and mix until it begins to dissolve into the meat mixture
Add the broth and bring to a simmer
Let it continue to simmer uncovered for 5-10 minutes. You are looking for 80% of that broth to reduce down. You do not want much liquid left so make sure to stay close and stir often.
Once it's mostly reduced remove from the heat and serve on with your favorite additions.
