Preheat your oven (or toaster oven) to 450°F. In a small bowl, combine the coconut aminos, orange juice, rice vinegar, fish sauce, and sesame oil. (Or, you can use 2 tablespoons of All-Purpose Stir-Fry Sauce in place of these ingredients for the marinade!)
Stir in the minced ginger and sliced mushrooms. Set aside.
Season both sides of the fish fillet with salt and pepper.
Take a large sheet of parchment paper and fold it in half. Draw half a heart on the paper so that when you cut it out, you get a full heart.
Open your heart and tile the three slices of orange on one side of the heart.
Place the seasoned fish filet on top of the orange slices.
Spoon the mushrooms and sauce on top of the fish and add the green onion stalks.
Fold the other half of the parchment heart on top of the fish and begin tightly crimping the edges together, starting at the top-center of the heart.
Make sure the packet is tightly sealed by turning and crimping the edges. At the pointy bottom end of the heart, twist the paper tightly to seal well.
Place the packet on a rimmed baking sheet and place it in the oven for 10-15 minutes or until the fish is cooked through.
Use a pair of kitchen shears to cut open the packet (but be careful—it’s hot!).
Remove the wilted scallions, and top with freshly minced cilantro and slivered green onions.
Plate it up if you’re feeling fancy and enjoy!
