Preheat oven to 425 degrees F.
Slice the sweet potatoes carefully into thin slices about 3/4 of the way through, making sure you don't slice all the way through.
Place the potatoes on a baking dish.
Rub ghee all over the potatoes and carefully between the slices.
Sprinkle generously with sea salt, making sure to salt between the slices.
Bake for 50 minutes, or until the slices are cooked through and tender.
While the sweet potatoes are baking, heat a frying pan over medium heat.
Dice the bacon slices into small bits, and cook them in the heated pan until they are brown and crisp.
