To make the marinade, combine the lime
juice and garlic in a blender, on low speed. Slowly add the ⅓ cup olive oil and
blend until mixed. Add the salt and spices. Pulse once to combine.
Pour the marinade into a zip-seal plastic
bag. Add the shrimp, tossing to coat. Refrigerate for 15 minutes.
In a small bowl, toss the bell peppers and
onion in 2 teaspoons olive oil until coated. Arrange them on a baking pan in a
single layer.
Roast for 10 minutes.
When the peppers are finished roasting,
remove them from the oven.
Use the slotted spoon to remove the shrimp
from the marinade. Sprinkle the shrimp on top of the roasted veggies.
Roast the shrimp and veggies until pink
(about 8 additional minutes).
