Preheat the oven to 425 F. On a cutting board slice the fingerling potatoes lengthwise and slice the white onion into rings. Add the potatoes and onion to a medium mixing bowl. Add the 2 tbsp extra virgin olive oil (EVO) and lightly salt and pepper. Line a large rimmed baking sheet with parchment paper and place the chicken skin side up on the baking sheet. Drizzle the marinade over the chicken and roast in the oven for 20-25 minutes. Open the oven and add the potatoes and onions around the sides and nestled in between the chicken and cook for an additional 20-25 minutes. Chicken will be cooked, crisp, and flavorful and the potatoes will be tender and fork friendly. Garnish with orange and lime wheels.
