Heat the oven to 375 degrees, and grease a 9×13 baking dish.
Line the baking dish with the crescent roll dough, pinching the seams together.
Cook the ground beef until completely browned, and drain any excess grease.
Stir in the taco seasoning, and simmer for 2-3 more minutes.
Place the refried beans in a microwave safe bowl, and heat for a few minutes.
Spread the beans over the dough in the dish, and then top with the meat. Bake for 20 minutes.
Top with the tomato, olives and cheese, and bake another 5-10 minutes, or until the crust is browned and cooked through.
Garnish with green onions before serving.
Enjoy!
