In a 9 X 9 glass or metal pan. Layer the bottom of the pan with refried beans. Add the taco seasoning to the sour cream and stir. Add the mixture over the refried beans, layer with cheese, diced tomatoes, green onions and handful of olives.
For the cheese, tomatoes, green onions and olives you can add more if you desire.
You can double the recipe and use a 9x13 pan if you need it for a bigger group. I've made both sizes.
