For the salad: In a large mixing bowl, combine the kale, radishes and fennel. Add the olive oil, lemon juice, zest and a pinch of salt, and toss to combine. Set aside.
For the dressing: Add a pinch of salt to a large wooden salad bowl. Rub the inside of the bowl with the garlic clove, using the salt as an abrasive. Add the anchovy and mash with the back of a spoon. Add the yolk and olive oil, and whisk to combine. Add the kale mixture to the dressing and toss to coat.
For the topping: Mix the breadcrumbs with the Parmesan and parsley, and sprinkle on top of the salad.
