Preheat your oven to 425 degrees f. and line a large rimmed sheet pan with parchment paper.
In a large bowl, combine your shrimp together with your oil, garlic, lime juice, lime zest and all seasonings.
Transfer mixture to your prepared sheet pan and arrange in a single layer.
Bake until your shrimp are pink and opaque, about 10 -12 minutes.
Once your shrimp are done cooking, remove from oven, then top with tomatoes, avocado, and cilantro leaves as shown if desired.
Enjoy!
