Preheat oven to 350 degrees Fahrenheit. Line a baking sheet with Gefen Parchment Paper.

Place fish on the baking sheet (if using frozen fillets, thaw before using). Season with salt and pepper to taste.

In a saucepan, mix together orange juice, maple syrup, soy sauce, vinegar, brown sugar and cornstarch slurry. Heat over low heat and bring to a simmer to thicken, about eight minutes.

Brush over the fish. Arrange two half-slices of orange over the top.

Bake uncovered for 18 minutes, then broil for three minutes.

If desired, garnish with pepper flakes, chopped parsley, or cilantro. Serve hot.
