Cook the ground beef in a skillet over medium heat until browned, then drain any excess fat and stir in the taco seasoning with a splash of water. Simmer for two minutes and set aside to cool slightly.
Spread the refried beans evenly across the bottom of a medium serving bowl to form the first layer.
Add the seasoned beef on top of the beans as the second layer, smoothing it out with a spoon.
Sprinkle the shredded cheddar cheese over the beef to create the third layer.
Spread the sour cream over the cheese for the fourth layer.
Add the mashed avocado as the fifth layer, followed by the salsa as the sixth layer.
Finish with the sliced black olives and chopped green onions scattered across the top as the seventh layer and garnish.
