Remove leaves from cauliflower.
Be sure your cauliflower is clean and free of dirt.
Using a sharp bread knife or offset serrated knife, cut cauliflower lengthwise two inches thick.
Be sure to leave florets attached to the main stem. Set oven to 400 degrees.
Using a large heavy bottom saute pan, bring to high heat, smoking hot and carefully place cauliflower steaks two at a time.
After two minutes drizzle 1/4 cup avocado oil over the top of cauliflower. Place on baking sheet and roast in the oven until golden brown (five to ten minutes depending on oven).
Remove from oven and sprinkle ground turmeric, Kosher salt, and juice of two lemons. Garnish with chopped parsley.
Serve two steaks with Wanderspice Sauce, per person.
