Mix spinach mixture ingredients together in mixing bowl.

Spoon one tablespoon of the spinach mixture onto the thin end of each fillet.

Roll fillet up into a circle around the spinach and stick in a toothpick to keep it together. Season with salt and pepper.

Place the fillet on its side, spiral side up, on a Gefen Parchment-lined baking sheet. Repeat for each fillet.

Bake for 15 minutes, covered, in a preheated 350-degree-Fahrenheit oven. Serve warm or at room temperature.
