make quinoa according to package instructions

toss sliced onion, lime juice, sugar and salt in a small tupperware container. cover, shake and set aside

place rack on the highest position in the oven and turn broiler on. in a medium mixing bowl, toss pineapple with 1 tbsp olive oil.

spread pineapple in a single layer on half of a large baking sheet and broil for approximately 8 minutes. (make sure to watch as things tend to burn quickly in the broiler)

toss shrimp, sriracha and 1 tbsp olive oil in a mixing bowl until shrimp are evenly coated.

remove baking sheet from broiler and flip pineapple. add shrimp to other half of baking sheet and broil for 2 minutes. after 2 minutes flip shrimp (don't touch pineapple) and broil for another 1-2. (if your shrimp are springy to the touch they are done!)

transfer shrimp and pineapple to a large bowl and season with salt and pepper (to taste) and the liquid from onion tupperware.

serve shrimp/pineapple over quinoa and top with onions and avocado! Enjoy!
