In medium bowl, measure out breadcrumbs. Add microplaned or finely minced garlic, minced anchovies, grated parmesan, and lemon zest, if using. Add about 1 TBSP of oil - just enough that when you grip the stuffing, it holds lightly together - like a streusel.
Taste stuffing, and add salt or pepper to taste.
Take an artichoke, and place it in a small bowl (this will catch any excess breadcrumbs). Working outside in, stuff breadcrumb mixture down into space between leaves. Once you've worked your way into the center of the artichoke, top with generous amount of breadcrumbs, and set aside. Do the same with each artichoke.
