In the meantime, add shrimp to a bowl and toss with marinade. After 10 minutes, take pineapple and veggies out and toss around, still keeping them separated.
Add shrimp to other side of pan. Cook for another 5 minutes, and then change oven to broil. Broil until edges of peppers start to brown, about 7-8 minutes.
Take out, let cool, then enjoy wrapped up in a tortilla. You could also enjoy on top of a salad, or with whatever suits your fancy with all your favorite toppings!
