In a pan brown ground beef until cooked through, about 10 minutes. Make sure to break up the ground beef so that it is in fine pieces. When finished cooking, stir in taco seasoning.
In a small bowl mix together greek yogurt and neufchatel cream cheese.
In an 8x8 baking dish, assemble the dip. Create the layers of cream cheese/yogurt, beef, refried beans, olives, corn and cheddar cheese.
Bake at 350 for 20-25 minutes until the top is bubbling and the cheese is melted!
