01 - Pat the salmon fillets completely dry with paper towels and season lightly with salt on both sides. Set aside at room temperature while preparing other ingredients.
02 - Heat the vegetable oil in a large skillet or wok over medium heat. Add the sliced onion and sauté for 2 minutes until slightly softened and translucent.
03 - Stir in the minced garlic, ginger, and green curry paste. Cook for 1 minute, stirring constantly, until fragrant and the paste is well combined with the oil.
04 - Add the zucchini, bell pepper, and sugar snap peas to the skillet. Stir-fry for 2 minutes until vegetables begin to soften but still retain crunch.
05 - Pour in the coconut milk. Add fish sauce, brown sugar, and bruised lemongrass stalk. Bring to a gentle simmer, stirring to incorporate all ingredients.
06 - Nestle the seasoned salmon fillets into the sauce. Cover and cook for 8-10 minutes, or until the salmon is just cooked through and flakes easily with a fork. Do not overcook.
07 - Remove from heat. Discard the lemongrass stalk. Squeeze fresh lime juice over the curry and stir gently to distribute the bright acidity.
08 - Plate the curry hot over freshly steamed jasmine rice. Garnish generously with fresh cilantro leaves, sliced red chili, and additional lime wedges on the side.
