Grease the bottom of a baking dish large enough to hold all the fish you are cooking.
Rinse salmon and pat dry.
Sprinkle salmon with garlic powder, salt, and pepper.
Zest orange carefully over the salmon filets.
With a knife, remove the remaining peel from the outside of the orange to expose the flesh.
Thinly slice the oranges across the sections.
On a cutting board, put a large chard leaf. If you can, slice the rib partially out and cut off the stem to make the leaf more bendable.
Place a piece of fish in the middle of the chard leaf, then thinly slice one tablespoon of butter and put on top of the fish.
Put several of the orange slices on top of this.
Wrap each chard leaf around the fish like you would wrap a gift and place seam-side down on the baking dish. Use another chard leaf if needed to make sure fish is completely wrapped.
Repeat with other chard and fish.
Sprinkle the tops of the wrapped salmon with sea salt and place in the oven.
Bake 15-17 minutes or until fish is cooked through.
Enjoy!
