Heat 1 tablespoon oil in a large skillet over medium-high heat. Add gnocchi; cook 5-8 minutes until golden and plump, stirring halfway through. Remove and set aside.
In the same skillet, add the remaining oil. Season salmon generously with salt and pepper. Cook over medium-high heat, about 6 minutes per side or until done as preferred. Use your spatula to gently break the salmon into large flakes..
Reduce heat to medium. Stir in the peas, mustard, and white wine. Add back the cooked gnocchi and some Parmesan cheese. Season to taste with salt and pepper.
Mix in the fresh herbs and finish with a squeeze of lemon juice.
Plate immediately and serve with additional Parmesan and black pepper.
