Peel the sweet potato and dice it into small, uniform 1/2-inch cubes to ensure even cooking.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat until shimmering.
Add the sweet potato cubes to the skillet and sauté for 8-10 minutes, stirring occasionally, until they are tender and golden brown on the edges.
Push the potatoes to the outer edges of the pan and add the lean ground turkey sausage to the center.
Cook the sausage for 5-7 minutes, breaking it into small crumbles with a spatula, until it is fully browned and no longer pink.
Add the diced red bell pepper and yellow onion to the pan, stirring everything together to combine.
Sauté the mixture for another 4-5 minutes until the onions are translucent and the peppers have softened.
Sprinkle the sea salt, black pepper, garlic powder, and smoked paprika over the hash and toss well to coat all ingredients.
Add the fresh baby spinach to the skillet and fold it into the hot mixture for about 60 seconds until just wilted.
Remove the skillet from the heat and serve the hash warm in a bowl.
