Preheat oven to 400. Add breadcrumbs and cheese to a large bowl and mix together.
Dip cauliflower pieces in egg, then roll in bread crumbs. Place on a non-stick baking sheet or a baking sheet lined with parchment paper. Drizzle olive oil over the top of the cauliflower before baking to prevent breadcrumbs from drying out.
Bake for about 20-25 minutes or until coating is golden brown and crunchy. Serve with marinara sauce.
