Heat oil in a oven safe skillet or cast iron. Add the sweet potatoes and sauté on medium low for about 10 minutes. Just enough to lightly soften and give the sweet potato a head start. Remove from heat.
Add in the remaining ingredients including spices and bake for about 25 mins. Remove from oven and sprinkle with mozzarella cheese. Bake for an additional 3-5 minutes, just enough to melt the cheese. Garnish with fresh cilantro (or herb of preference) and serve.
