Start by heating up your skillet to medium heat. A cast iron skillet is ideal, but any large pan will do the trick.
Add your ground turkey to the skillet along with the minced garlic. Let the turkey brown while soaking up that garlic flavor—this usually takes about 5-7 minutes.
Once the turkey is browned, toss in your diced onions and yellow pepper. Sauté everything together until the onions soften, which takes another 3-5 minutes. At this point, your kitchen is going to start smelling amazing!
Add in your diced sweet potato, along with the salt, pepper, and red chili flakes. Cover the skillet and let everything cook until the sweet potatoes are nice and tender, which should take around 10-12 minutes. Make sure to stir occasionally so nothing sticks. If things seem dry, don’t hesitate to add a splash of water to help the sweet potatoes cook faster.
While the sweet potatoes are cooking, go ahead and preheat your oven to 400°F. Once the sweet potatoes are soft, sprinkle the shredded mozzarella cheese over the skillet, then pop it into the oven to melt the cheese. This will only take about 2-3 minutes, but keep an eye on it!
Once the cheese is melted and bubbly, pull the skillet from the oven. Garnish with freshly chopped parsley and you’re ready to serve!
