Place a large pot on your stove over medium-high heat. Add in some Vegetable Oil (to taste), Yellow Onion (1), Garlic (2 clove) and cook for a couple of minutes or until the onions start to soften slightly.
Next add in the Ground Beef (1 kilogram) and break it down using a wooden spoon. Cook for about 5 minutes or until the meat has browned.
Drain any excess grease from the ground beef. Add Taco Seasoning (40 gram), Taco Sauce (1 cup), Water (2 cup), Beef Stock (4 cup) and give it a good stir.
Add in the Elbow Macaroni (500 gram) and give it a gentle stir. Once the pot comes up to a boil, turn the heat down to low and let it simmer uncovered for about 15 minutes, while giving it a stir every few minutes.
Raise the heat back up to medium and continue to gently stir until almost all the liquid has been absorbed. Turn off your heat. Season at this point with Salt and Pepper (to taste).
Add in Cheddar Cheese (3 cup) and incorporate gently until cheese melts through. Serve with toppings of choice and enjoy.
