Preheat an oven to 375 degrees Fahrenheit. Line a baking sheet with parchment paper. Place the sweet potato rounds on the baking sheet and brush them lightly with olive oil and sprinkle with salt. Bake them for 20-25 minutes, flipping them over halfway through cooking.
While the sweet potatoes are cooking, cook the bacon. Heat a large skillet to medium-high heat and cook the bacon in the skillet until it is cooked through. Remove from pan and drain on paper towels. Slice into thirds.
In a large mixing bowl, combine all of the meatball ingredients together and mix well until all ingredients are well combined. Coat your hands with a small amount of olive oil and roll the meat into 1-inch meatballs and place on a baking sheet lined with parchment paper. Bake for 15-18 minutes, until the meatballs are cooked through.
To assemble: Layer the bacon slices on top of the sweet potato rounds, then top with meatballs. Skewer with toothpicks to hold in place. Serve and enjoy!
If you plan on making this ahead of time, you can store these in the fridge, and prior to serving heat an oven to 350 degrees Fahrenheit and bake for 15 minutes.
