Toasted Panko
Heat a medium skillet over medium heat. Melt the butter.
Add the breadcrumbs, oregano, parsley, red pepper flakes, and salt. Toast, stirring often for 5-6 minutes, until the breadcrumbs are golden brown.
Transfer the breadcrumbs to a plate or bowl to stop the cooking process and allow the breadcrumbs to cool.

To convert stovetop pasta cooking times for a pressure cooker, divide the lowest number on the package cooking time by half and then subtract a minute or two.
