Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper. Toss the sweet potato slices with olive oil, salt, black pepper, and cinnamon (if using). Arrange them in a single layer on the baking sheet. Roast for 20-25 minutes, flipping halfway through, until golden brown and tender.

Step 2: Assemble the Toppings

Once the sweet potatoes are done roasting, transfer them to a serving plate. Sprinkle each round with crumbled feta cheese, drizzle with honey, and add a pinch of red pepper flakes if you like a bit of heat. Garnish with fresh parsley or thyme and chopped nuts for extra texture.

Step 3: Serve and Enjoy

Serve immediately while warm. These rounds can be enjoyed on their own or paired with a protein for a more substantial meal.
