Preheat your oven to 400°F.
Peel and dice the sweet potatoes into small bite-sized pieces.
In a mixing bowl, combine the sweet potatoes, olive oil, salt, black pepper, garlic powder, cinnamon and paprika. Mix until the sweet potatoes are coated in the spices.
Spread the sweet potatoes in a single layer on a baking sheet and roast for 20-25 minutes or until they are golden brown and tender.
Dice a red onion and saute the onion until translucent and sweet to taste.
While the sweet potatoes are roasting, prepare the dressing by whisking together the lemon juice, honey, and Dijon mustard in a small bowl.
Once the sweet potatoes are done, remove them from the oven and let them cool for a few minutes.
In a large mixing bowl, combine the roasted sweet potatoes, sauteed red onion, chopped roasted red peppers, fresh parsley, crumbled-up feta cheese and the dressing.
Enjoy at room temperature or cool.
