In food processor, blend basil, garlic, Parmesan cheese, and pecans to form dry paste. Add enough olive oil to produce a runny paste. Scrape into bowl and add bread crumbs until crust has a slightly moist crumb texture. Set aside.
Preheat oven to 375F. Season salmon with salt and pepper. Apply a thin (about 1/8-inch) coat of crust to meat side of each fillet. Place salmon in baking dish, pesto-side-up, and drizzle with olive oil. Bake until desired doneness, about 8-10 minutes per inch of thickness of fish. Place fillets on plates. Drizzle with tomato oil.
