Preheat oven to 400°F. Pour 2 Tbsp. olive oil into a large skillet set over medium-high heat. Sear steaks, in batches, 2 minutes per side, until golden brown, and then set on a baking sheet. Season steaks with your favourite herb/spice blend. Roast until tender, about 15 minutes. If desired, serve cauliflower with a sauce, such as marinara, curry or harissa.
