Roasted and Charred Broccoli with Walnuts

Preheat oven to 450º. Slice the broccoli stems on a diagonal, 1/4-inch thick. Toss them with oil and season with salt and pepper. Transfer them to a baking sheet and roast them until browned at the edges, about 15 to 20 minutes. Put them in a bowl and toss with vinegar. Set them aside.

Heat some olive oil in a skillet and sauté the leeks until completely soft. Add these to the broccoli stems. Add additional salt or pepper to taste.

Heat a skillet over medium-high, gather up the loose pieces of florets and chop them fine. Add the florets to the un-oiled pan and cook them, stirring often until bright green and lightly charred in spots, about 5 minutes.

Serve the broccoli stems topped with the florets and walnuts. Sprinkle on the capers if you want to use them.
