Preheat the oven to 400 degrees Fahrenheit (204 degrees Celsius) and line a high-rimmed baking sheet with parchment paper or silicone mat.
In a small mixing bowl, whisk together the honey, olive oil, minced garlic, soy sauce, salt, black pepper, and dried oregano until emulsified.
Place the sliced sausage and cubed sweet potatoes on the baking sheet.
Pour the honey garlic mixture over the ingredients and toss using tongs or clean hands until every piece is evenly coated.
Spread the ingredients into a single layer, ensuring no overlapping to allow for proper caramelization.
Place the baking sheet in the center of the oven and roast for 25 minutes, pausing halfway through to toss the ingredients for even browning.
Verify that the sweet potatoes are fork-tender and the sausage is lightly browned before removing from the oven.
Garnish with fresh chopped parsley and serve immediately.
