Heat the olive oil in a generously sized skillet over medium-high heat until the oil reaches a desired temperature
Add the ground beef, garlic, bell pepper, and onion to the skillet.
Sprinkle the mixture with chili powder, salt, and pepper to season.
Cook, breaking up the beef as it cooks until it reaches a fully cooked state, which should take approximately 6 to 8 minutes.
Add the beef broth, macaroni, ketchup, mustard, brown sugar, and hot sauce into the skillet.
Stir thoroughly to ensure all the ingredients are well combined and allow the mixture to come to a simmer.
Cover the skillet and let it cook until the macaroni softens, and the sauce achieves a desirable thickness, which will typically take around 9 to 10 minutes.
Remove the skillet from the heat source.
Add the cheese and gently stir until it melts and blends into the mixture.
Serve your dish with a garnish of fresh parsley.
