Preheat the oven to 450 degrees. Toss the cauliflower with a drizzle of oil and a pinch of salt. Roast for 30 minutes.
Blend everything in a food processor or blender until smooth. Simmer in a saucepan over low heat until it thickens slightly.
Pour sauce directly onto the roasting pan – just enough to get the cauliflower nice and saucy. Toss gently to combine.
Pretty: Arrange the sauced up cauliflower in lettuce cups. Top with extra sauce, crushed peanuts, chives, and a drizzle of spicy mayo. Mwah!
