Place stale bread in a food processor and blend until fine crumbs form. Measure out 1.5 to 2 cups of crumbs. Heat 2 tablespoons of olive oil over medium heat. Add the bread crumbs and 1/4 teaspoon kosher salt. Cook, stirring occasionally, until golden brown. This may take 5 to 15 minutes, depending on heat level. Allow to cool briefly, adjust salt if necessary, and measure out 1/3 cup crumbs for the salad.

Add the sliced asparagus and toss to mix. Adjust seasoning by adding more salt, pepper, red pepper flakes, or lemon juice as needed. When the flavors are balanced and bright, add mint (if using) and 1/4 cup olive oil. Toss again, taste, and make final seasoning adjustments.
