Toss potatoes in olive oil and season well with salt and pepper. Arrange potatoes on a lined baking sheet, trying not to overlap too much.
Bake potatoes for 15-25 minutes or until tender and the edges are golden brown and crisp.
While potatoes are baking, brown turkey bacon in a large skillet over medium high heat until crisp. Cut bacon into pieces.
Top baked potatoes with cheese, bacon, scallions and olives. Return to oven and bake an additional 3-5 minutes or until the cheese is melted and bacon is heated through. Serve with sour cream.
