Step 1

Preheat oven to 450°. In a 15x10-inch baking pan, toss cauliflower with a glug (2 to 3 tablespoons) of oil; spread evenly and season with salt and pepper. Roast until golden brown, crispy and tender when poked with a knife, about 20 minutes.

Step 2

Meanwhile, in a second 15x10-inch pan, toss tomatoes with a glug (2 to 3 tablespoons) of oil and a pinch of salt; spread evenly. Roast, stirring regularly, until liquid is reduced and syrupy, about 20 minutes.

Step 3

Transfer roasted cauliflower to a large serving bowl. Add the tomatoes, parsley, and olives; toss to combine. Top with Garlic Breadcrumbs.
