Once the griddle is hot, add the ground beef and chopped onions to the griddle. Cook and break up the ground beef until it’s no longer pink and broken into small pieces.
Sprinkle the top of the ground beef and onions with the taco seasoning and salsa. Add the water to the mixture and stir to combine all the ingredients.
Spread the tortilla chips onto a baking sheet. Top the tortillas with half the cheese, ground beef mixture, beans and then the remaining shredded cheese.
