Step 2Stem the cauliflower and cut it down into small florets. Place in a large bowl and toss with the olive oil and 1 to 2 teaspoons salt, or to taste, along with several grinds of pepper.
Step 3Spread the cauliflower onto a rimmed baking sheet and roast until the cauliflower is tender and lightly browned, 35 to 50 minutes.
Step 4Plate the roasted cauliflower, garnishing each serving with smoked almonds. Serve immediately.
