Preheat oven to 400 f. Heat a little oil in a cast iron skillet. Place fillet in pan, spice side down, and brown 2 minutes. Turn fillet and bake until it flakes, about 5 minutes. Don’t overcook.
Alternatively, drizzle with oil and broil on high 5 minutes. take out and let sit 5 minutes.
OR steam over bed of fresh herbs in a steamer basket for 10 - 15 minutes alongside greens.
Serve on a bed of dark, leafy greens. Perhaps top with a yummy cilantro pesto or Parsley Pesto. Make up a few lets to use for later in the week with other dishes (like you will with the Simple Roasted Chicken).
