To make breadcrumbs from scratch:
Process 6 large bread slices in a food processor to get coarse crumbs. Heat up a pan and add the bread. Stir for a few minutes, add one tablespoon oil and stir until the bread is dry and golden. Let this cool and then put it back in the food processor. Add 1 tsp dried rosemary, 1 tsp dried oregano, 1 tsp dried basil, 1 tsp dried parsley, 1/2 tsp garlic powder, 1/2 tsp salt and 1/4 tsp ground black pepper. Process until fine. If you’re using store bought breadcrumbs, put them in a pan with a little oil for a few minutes just to get some color on them.
