Mixed the buttermilk with the egg, and soaked the green beans in the mixture for about 10 minutes in the fridge (hoping for a little extra sticking power).
Then, we arranged the green beans on a pan, lined with foil and sprayed with cooking spray (foil not necessary).
Then, we sprinkled the beans with salt and panko crumbs.
Then, place in oven at 400 degrees for about 10-15 minutes, or until panko starts to get golden brown.
