Broccolini with Pine Nuts and Lemon

1/4 cup pine nuts

2 tablespoons unsalted butter

1 lemon, thinly sliced

2 bunches broccolini

4 tablespoons olive oil, divided

2 cloves garlic, thinly sliced

1/2 cup finely grated pecorino

Salt and pepper to taste

In a large dry skillet over medium heat, toast pine nuts until beginning to brown, about 2 minutes. Transfer to a bowl. 

In the same skillet over medium heat, melt butter. Add lemon slices and cook until tender and lightly browned, about 3 minutes per side. 

Transfer to a plate. 

Add half of olive oil to pan. Working in batches, add half the broccolini to the pan. Cover and cook, flipping once, until beginning to brown, about 4 minutes per side. Repeat with remaining olive oil and broccolini. 

Add garlic to pan and cook 30 seconds, then add broccolini back to pan. Add lemon slices and pine nuts. Toss to mix, then season lightly with salt and pepper. 

Transfer to a serving plate and top with pecorino. Serve hot.
