Cook 1 lb of hamburger. Drain fat off. Take a large mixing bowl and mix drained hamburger, 1 can of refried beans, 1 pkg taco seasoning mix, 1/2 of taco sauce(large jar). Spread mixture in bottom of a 9x13 pan.
In a small mixing bowl, mix in remaining taco sauce(1/2 jar) and 1 cup of sour cream. You will spread this mixture over top the meat mixture.
You will take the large package (2 cups) of mexican blend shredded cheese and spread over top of sour cream mixture.
Place the 9x13 pan into a pre-heated 350 degree oven. Bake for 30 mins. or until cheese is bubbly. Remove from oven and let stand for approx. 10 mins.
Serve with your favorite type of tortilla chips. Scoops work the best.
