Preheat the oven to 425. Line a baking sheet with foil and spray with cooking oil Place the cashews, cheese, oil, juice and garlic in the bowl of a food processor and process just until coarsely ground. Do not puree. Place the fish on the prepared baking sheet and divide the nut mixture overtop, pressing it onto the filles to help it adhere. Bake for 10 minutes per inch of thickness, or until the fish flakes when pierced with a fork. Garnish with the dill and lemon wedges
