Brown hamburger in a skillet, cook until done, drain, and set aside.
Arrange nacho chips evenly to cover the bottom of a cookie sheet (10×15 inch) in one layer.
Preheat oven to 400 degrees Fahrenheit. Combine cooked hamburger, tomato, ½ cup cheese, salsa and cheese salsa in a large mixing bowl. Allow the burger to crumble and mix.
Spread mixture evenly over nacho chips and sprinkle green onions and cheese on top. Place in the middle of the oven and cook for approximately 10 minutes or until cheese on top has melted. Place oven on broil for 1 minute or until cheese bubbles.
Take out of the oven and serve immediately with sour cream and salsa on the side for dipping. Enjoy this quick and easy recipe that will soon become a family favourite!
