01 - Pat the salmon fillets dry with kitchen paper. Season both sides generously with salt and pepper.
02 - Heat olive oil in a large non-stick frying pan over medium-high heat until shimmering.
03 - Place the salmon fillets skin-side down in the hot pan. Use a spatula to gently press down for 10 seconds to prevent curling.
04 - Cook skin-side down for 5–6 minutes, until the skin is crisp and the fish is cooked about two-thirds of the way up.
05 - Flip the salmon fillets. Add butter and garlic to the pan. As the butter melts, tilt the pan and spoon the foaming butter over the salmon for 1–2 minutes, until the salmon is just cooked through.
06 - Add capers and lemon juice to the pan. Spoon the sauce over the fish to coat evenly.
07 - Remove from heat. Sprinkle with chopped parsley and let rest briefly.
08 - Meanwhile, blanch the broccoli or asparagus in boiling salted water for 2–3 minutes until just tender.
09 - Serve the salmon immediately with the vegetables and lemon wedges.
