In a food processor, blend the cashews, cilantro, 1 tablespoon (14 g) of coconut oil and salt, until even, green crumbles are formed.
In a medium nonstick skillet, heat the remaining 1 tablespoon (14 g) of coconut oil over high heat, then place the salmon fillets in the pan, skin side down. Immediately spread the cashew crumbles on top the fillets, pressing them down onto the fish and creating a crust about ⅛ to ¼ inch (1 to 2 cm) thick. Cover and cook until the salmon is turning opaque all over, about 5 minutes, then turn off the heat and let sit for another minute.
While the salmon is cooking, make the ponzu sauce by mixing the coconut aminos with the lime juice.
Serve hot with a couple of tablespoons of ponzu sauce on top of the salmon. This is great with Salt and Pepper Asparagus (page 115) on the side.
