Preheat the oven to 400 degrees Fahrenheit (375 degrees for convection ovens).
In a bowl, mix together chopped cashews, coconut, panko, avocado oil, salt, pepper, sriracha, smoked paprika, and garlic.
Put your choice fish on a sheet tray lined with parchment paper. Add half of the mixture to the top of each piece of fish (approximately 1/4 cup each), pressing down so that the topping adheres to the fish.
Place in your preheated oven, cooking for about 6-8 minutes, depending on thickness and so that the internal temperature reads around 145 degrees.
