Combine the olive oil, crushed red pepper, thyme, garlic and lemon zest in a medium bowl, and then massage over the fish. Sprinkle with salt, and set aside to marinate, 15 to 20 minutes.
Rub off any excess herbs to prevent burning. Coat a medium saute pan with olive oil and bring to high heat. When the oil is hot, add the fish skin-side down. Resist the urge to try to move the fish. Cook 3 to 4 minutes, and then gently shake the pan to allow the fish to unstick itself. Carefully flip and continue cooking until just cooked through, about 4 minutes more. Serve with the Salsa Verde.
Combine the vinegar, olive oil, pine nuts, dill, red pepper, salt, garlic, parsley, zucchini and onions in a medium bowl. Taste and season with more salt, if necessary. Serve at room temperature.
