1.Preheat the oven to 185°C. In a food processor, combine the spinach, herbs, garlic, lemon juice and zest, then pulse until finely chopped. Add the oil and salt, then blend until bright green and smooth. Transfer to a jar.
2.Line a baking tray with cooking paper. Arrange the salmon fillets on the paper and spray with oil. Sprinkle with dukkha and bake for 8-10 minutes, depending on the salmon thickness. The flesh should be just starting to flake in the centre.
3.Heat a large saucepan of water and cook the pasta until al dente, adding the beans for the last minute of cooking.
4.Drain and toss with the tomatoes and a few tablespoons of the green sauce. Arrange the pasta in piles on the plates and top with the salmon fillets. Garnish with Parmesan cheese, to taste.
