Roasted cauliflower shares a plate with olives and stuffed peppers for a tasty appetizer that's simple to make.
Preheat oven to 400 degrees. Divide cauliflower and capers between 2 rimmed baking sheets. Drizzle each sheet with 3 tablespoons oil; toss to combine. Season with salt. Spread in a single layer. Roast, stirring occasionally, until cauliflower is golden brown and tender, 30 to 40 minutes. Toss with marjoram. Serve warm or at room temperature, drizzled with oil.
