For the pesto, bring a pot of water to a boil; salt it and add kale. Cook for 1 full minute, then remove with tongs to a cold water bath to cool and squeeze out all the liquid in a clean kitchen towel. Add the dry kale, now 2-3 cups total, to a food processor along with the EVOO, cheese, anchovy paste, garlic, nuts, Worcestershire sauce, Dijon and the juice of 1 lemon. Process the pesto sauce until almost smooth. Use on fish, meat or pasta.
For fish, pre-heat the oven to 400°F. Place a rack one level above center. Arrange the fillets skin-side down on a nonstick or parchment-lined baking sheet and season with seafood seasoning. Spread an even layer of pesto across each fillet, covering the flesh completely. Roast until the fish is white, flaky and opaque, 15-18 minutes. For an outdoor grill, soak wooden fish boards in water, then arrange 1 fillet on each board and top with fish seasoning and pesto. Grill over medium to medium-high heat, covered, until the fish is white and flaky. Squeeze the juice of the remaining lemon over the cooked fish and serve.
For the steak or chicken, place the EVOO, garlic, rosemary, scallions and lemon slices in a large resealable plastic bag. Season the steaks or chicken with salt and pepper, add to the bag and marinate for a few hours or up to overnight. Grill on a grill pan or outdoor grill over medium-high heat, 12 minutes for chicken and 8-10 minutes for steak 1-1 1/2-inches thick. Let the meat stand for a few minutes, then slice on an angle for chicken or against the grain for steaks. Top with the pesto sauce; serve with warm crusty bread alongside.
