Bitter Greens with Anchovies and Breadcrumbs

Heat 2 tablespoons oil in a small skillet over medium. Add bread and cook, stirring often, until golden and crisp, 4 to 6 minutes. Drain on paper towels, then transfer to a small bowl. Stir in cheese; season with salt and pepper. Wipe skillet clean.

With the flat side of a heavy knife, mash garlic and anchovies to a fine paste. Heat remaining 1/4 cup oil in skillet over medium; add anchovy mixture and cook until warm and fragrant, about 1 minute. Transfer to a bowl; whisk in lemon zest and juice, and capers. Season lightly with salt and pepper; let cool completely.

Toss dressing with fennel and celery. Fold in greens and season with salt and pepper. Mound salad on 4 plates; top with breadcrumbs and avocado. Serve immediately.
