Step 1
In a large heavy sauté pan over medium-high heat, bring stock and wine to a boil. Reduce heat to medium-low, add salmon and cover pan. Steam salmon, flipping over halfway through cooking, for about 6 mins, or until salmon is just cooked through but still slightly rosy in the centre. Remove salmon from pan, sprinkle with salt and cover loosely with foil.
Step 2
Return liquid in pan to a simmer over medium-high heat. Add spring onions and garlic and simmer for 2 mins, or until onions soften. Add asparagus, peas, radishes and artichokes and cook, stirring frequently, for 3 to 4 mins, or until vegetables are crisp-tender. Remove from heat and stir in lettuce, butter and dill. Season with salt and pepper.
Step 3
Divide salmon, vegetables and cooking liquid among 4 plates and serve.
