Step 1

Preheat oven to 425 degrees. Line a 9 by 12-inch baking dish with parchment paper.

Step 2

Place cod fillet(s) in prepared dish and brush with lemon olive oil. Evenly sprinkle feta cheese, lemon zest and dill on top.

Step 3

Roast in the oven, uncovered, 8 to 10 minutes per 1-inch of thickness (at its thickest point), until opaque and just cooked through.

Step 4

Switch the heat to broil and broil for 2 minutes to melt and lightly brown some of the cheese. Watch carefully so it doesn’t burn!

Step 5

While the fish is cooking, in a large sauté pan or skillet, heat 2 teaspoons regular extra virgin olive oil over medium heat. Add green onions, garlic and around half of the spinach. Cook, stirring, just until the spinach is wilted. Add remaining spinach and continue to cook, stirring, just until wilted.

Step 6

Remove from heat and stir in breadcrumbs and red pepper flakes (if using); season to taste with salt and pepper.

Step 7

Divide cooked spinach among four serving plates. Top with cod fillet. Serve immediately.
