This Salmon and Green Pesto Papillote is an elegant yet incredibly easy low-carb salmon recipe that's packed with fresh Mediterranean flavours. Tender salmon fillets are baked en papillote (in parchment paper) with vibrant homemade green pesto, fresh lemon slices, and crisp green beans, allowing the fish to steam gently in its own juices while absorbing the delicious flavours of the herbs and citrus.
