Steps
1. Start by seasoning the trout fillet with salt and pepper on both sides.
2. In a small bowl, mix the Dijon mustard with a squeeze of lemon juice and set aside.
3. Heat the olive oil in a pan over medium heat. Once hot, add the trout fillet skin-side down.
4. Cook for about 3-4 minutes until the skin is crispy, then flip and add the butter to the pan.
5. Spoon the mustard mixture over the trout and cook for another 2-3 minutes until the fish is cooked through.
6. In a separate pot, blanch the seasonal vegetables for about 2-3 minutes until tender but still vibrant.
7. Serve the trout on a plate, drizzle the pan sauce over it, and arrange the vegetables alongside. Garnish with fresh parsley.
