  1. Preheat oven to 425°F.
  2. Line a large rimmed baking sheet with parchment paper or aluminum foil. (If using foil, spray with nonstick cooking spray.) Place cauliflower on prepared baking sheet, and brush “steaks” and florets with 2 teaspoons of oil. Sprinkle with pinch of salt and pepper. Roast until lightly caramelized and almost cooked through, about 18 minutes.
  3. Gently flip each “steak” and floret and brush with 1 more teaspoon of oil. Sprinkle with thyme, a pinch of salt and pepper and roast until well caramelized and cooked through, about 10 more minutes.
  4. While cauliflower is roasting, prepare pesto. Place olive oil, basil, sunflower seeds, mustard, honey and garlic in bowl of a small food processor and pulse until smooth. Season with salt and pepper to taste, and pulse a few more times until well combined and desired flavor is achieved.
  5. Arrange cauliflower on large plate or platter. Top with pesto, and garnish with sunflower seeds, thyme and basil.

Chef Tips

* How to Make Cauliflower “Steaks:”

  1. Rinse cauliflower and remove outer leaves. Pat dry with paper towels.
  2. Leave stem intact, but trim bottom so cauliflower stays flat and stable when placed on cutting board.
  3. Place cauliflower on cutting board with stable stem side down and use sharp chef’s knife to slice cauliflower in half.
  4. Starting at cut side of each half, carefully cut two, 1-inch-thick slices. Trim away stem ends.
  5. Break remaining cauliflower pieces into florets. (You should end up with three to four big steaks, a few mini steaks and a bunch of florets.)
