Cut the crusts off each slice of bread. Break the slices into pieces and put in a blender or food processor. Cover with a lid and grind the bread at medium speed in pulses of 5-10 seconds. After 40-50 seconds, the crumbs will be ready.
Put it in a bowl. Add salt, spices and herbs, mix. Transfer the crumbs to a baking sheet lined with parchment. Roast in preheated oven at 300 degrees F for 4-5 minutes, moving around halfway thru or until as toasty as you'd like.
Allow them to cool completely to crisp up. Transfer the Panko to a jar or container with a lid and store in a dry place.
