Brown the ground beef; drain grease. Dice the black olives and mix in with ground beef. Add tomato sauce to hamburger mix. Let simmer for about 5 minutes.
While that is cooking, in a medium size bowl, mix the bag of cheese, sour cream, and green chilies in a bowl and mix up.
Put the tortilla chips in the bottom of a pan. Once the beef mix is done cooking, take and put the meat over the chips. Once that is done put the sour cream mix on top. Then put a small layer of chips on top.
