If you can't find them at a grocery store, here's a simple way to make your own homemade breadcrumbs. Simply air dry a few slices of white bread, cut into cubes and pulse in a blender or food processor with 1/2 tsp of dried Italian seasoning, until the breadcrumbs are coarse or a texture you like. If you don't have time to air dry the bread, place the slices on a baking sheet in a low 200℉ oven. Check the bread every 10-15 minutes until it is completely dried out.
