To prepare the meat mixture, brown the ground beef and onion in a large skillet over medium heat, breaking up the ground beef as it cooks. Drain any excess fat and return skillet to stove top over medium heat.
Add in the taco seasoning, tomato sauce, drained pinto beans, chili powder, water and salt. Stir mixture and bring to a small simmer to allow flavors to blend.
Meanwhile, prepare your salad ingredients. Serve taco meat mixture over salad and corn chips, with any of the desired toppings you like. Enjoy!
The taco meat mixture is great for freezing for a later date. Let cool completely before freezing. Can be stored in freezer for up to 4 months. Defrost overnight in refrigerator.
