While the veggies roasted, marinated the shrimp with oil, chili powder, smoked paprika powder, garlic powder, onion powder, cumin, salt and lemon juice.
Take the roasted veggies out of the oven, arrange the shrimps on top of roasted veggies. Put the pan back in the oven, roast it for 10 minutes or until shrimp cooked and turned pink.
Use nonstick foil or parchment paper for easy cleaning.
