Add shrimp and jalapeño to a large glass or non-reactive bowl. Pour in the orange, lime, and lemon juice and stir to coat. Make sure all the shrimp is submerged.
Cover and refrigerate for 30 minutes.
Stir the shrimp gently, then return to the fridge for another 15–30 minutes or until opaque and fully “cooked” by the citrus.
Add strawberries, pineapple, avocado, and cilantro. Season with salt and pepper and toss gently to combine.
Serve with a slotted spoon to remove excess liquid. Garnish with lime wedges and enjoy immediately.
