Cook ground turkey in a medium skillet until done and add taco seasoning as directed by package. Optional: I like to add fresh onions and garlic to my meat while it's cooking. As well as a dash or cumin and smoked paprika for added depth of flavor. This is certainly not necessary if you don't have it on hand.
When meat is done, let cool, or refrigerate. I sometimes make the meat the day before a party and make extra to have tacos that night for dinner. This saves some time and kills 2 birds with one stone.
Once the meat is cold, you can start building your layers. I usually make mine in a 13x9 in pan, but anything with some depth will work.
Start with the re fried beans at the bottom, then the meat. After that the salsa, sour cream and cheese. Then sprinkle the top with olives and green onion.
