In a large skillet over medium-high heat, add one pound of ground beef, breaking it apart with a spatula. Cook for 6–8 minutes or until evenly browned, stirring occasionally. Drain any excess grease.

Once the beef is browned, stir in one diced yellow onion and cook for an additional 4–5 minutes until the onion is translucent.

Add taco seasoning, salsa, and shredded cheddar cheese to the skillet. Stir well and let it simmer for 6–7 minutes over medium heat.

Assemble your Taco Joes by spooning the savory beef mixture into hamburger buns, adding desired toppings.
