Spiralize zucchini, sprinkle some salt on the zucchini noodles, and place them between some towels to capture any excess moisture. Set aside.

Heat a skillet over medium-high heat. Add the ground beef, onion, and garlic. Break apart beef and cook for 5-10 minutes until beef is fully cooked and onion is softened.

Add the zucchini noodles to the skillet and stir. Cook for about 2 minutes then add the drained canned tomatoes and taco seasoning. Stir to coat noodles and cook another 2 minutes.

Stir in about 75% of the cheese and allow it to melt and incorporate. Sprinkle remaining cheese on top and serve.
