I am most certainly not taking any credit for this laughingly simple technique that impresses both in flavor, texture, and looks. My version coats a whole head of cauliflower in canola oil, and seasons it with smoked salt and freshly ground black pepper. Roast until crispy and dark brown on the outside, and tender inside. Serve a wedge over a smooth squash puree* (in this instance, kabocha) and garnish with a bright, fresh gremolata.
*I went all indulgent with butter and cream, but feel free to omit for a vegan version.
