Cook ground beef till brown. Drain well. Add taco seasoning and the salsa. Mix till combined. Pour meat mixture into a 13 x 9 baking pan. Top with corn chips, spread into an even layer. Then top with cheese, evenly spread on the top. Bake in a preheated oven at 350° for 15 - 25 minutes or until cheese is melted and bubbly. Remove from oven and top with your favorite toppings, sour cream, lettuce or anything else you like.
