Prepare Sweet Potatoes: Peel sweet potatoes and slice into ½-inch thick rounds.
Season: In a large bowl, toss sweet potato rounds with olive oil, salt, and pepper until well coated.
Preheat Oven: Preheat oven to 400°F (200°C).
Arrange: Line a baking sheet with parchment paper. Arrange sweet potato rounds in a single layer on the prepared baking sheet, ensuring they don't overlap.
Roast: Roast for 20-25 minutes, flipping halfway through, until tender and slightly browned. Check for doneness by piercing with a fork.
Cool Slightly: Remove from oven and let cool slightly for a few minutes.
Top: Sprinkle crumbled feta cheese evenly over the warm sweet potato rounds.
Drizzle: Drizzle honey over the feta-topped sweet potato rounds.
Add Optional Toppings: Sprinkle with chopped fresh thyme leaves and chopped walnuts or pecans, if using.
Balsamic Glaze (Optional): Drizzle with balsamic glaze, if using.
Serve: Serve immediately while warm.
