- With the rack in the middle position, preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Spread the sweet potatoes out on the baking sheet. Toss with 2 tbsp (30 ml) of camelina oil. Season with salt and pepper. Bake for 30 minutes or until the sweet potatoes are golden and tender. Add the green onions, cilantro and sunflower seeds to the baking sheet and continue cooking for 5 minutes.
- Just before serving, toss with the arugula. Drizzle with the remaining oil. Sprinkle with red pepper flakes, if desired.
