1. Cut 4 large sheets of parchment paper into a large heart shape (do this by folding the large sheet in half, then cut out a large 'half heart' shape) and set aside.
2. In a small mixing bowl, toss the julienned veggies with the garlic and parsley, along with some olive oil and salt/pepper to taste. Divide the veggies and place in the center of each parchment package, along the folded seam.
3. Top with a piece of fish, along with another splash of olive oil and salt and pepper. Place 1 tbsp of butter on top of each piece of fish, along with a sprig of fresh thyme. Add approximately 2 tbsp of white wine on top, then paint the edges of each parchment paper package with some egg white, using a pastry brush.
4. Seal each parchment package, then fold along the seal to create a tight parcel that will trap in the steam. Place each filled parchment parcel onto a sheet tray and bake at 400 degrees for 10 minutes.
5. Remove and cut open each parchment package to reveal perfectly steamed fish and vegetables! Garnish with a squeeze of fresh lime juice and serve with a side of rice... enjoy!
