Place the pan in the oven and allow the sweet potatoes to cook about 20-25 minutes.
While the sweet potatoes are cooking, prepare the remaining veggies, and peel and devein your shrimp.
In a bowl, combine the remaining chopped veggies and shrimp, and drizzle with the remaining oil.
Remove the pan from the oven, place the remaining ingredients on the baking sheet, and season with more salt and pepper, if desired. Bake for 15-20 minutes until shrimp is fully cooked through and pink.
