Step 1

Put the breadcrumbs, Parmigiano, walnuts, and lemon zest in a large bowl. Add 1 teaspoon salt, a bunch of twists of black pepper, and 1/2 teaspoon chile flakes. Toss to combine everything.

Step 2

Cut the asparagus on a sharp angle into very thin slices and add to the crumb mixture. Add 1/4 cup lemon juice and toss some more. Taste and dial in the flavors by adding more salt, black pepper, chile flakes, or lemon juice.

Step 3

When the flavors are bright and delicious, add the mint and 1/4 cup olive oil and toss. Taste and adjust again, and serve.
