Swap option: Replace shrimp with scallops or swordfish.
Preheat oven to 475°F and place a sheet pan inside to warm up.2.
Add stale bread, parsley stems and garlic to a food processor. Blitz the mixture until it looks like green breadcrumbs, then transfer to a bowl. In a separate bowl, whisk egg whites and salt.3.
Add shrimp to the egg white mixture, making sure they are well coated. Toss shrimp in batches in the green breadcrumb mixture, making sure they are well coated.4.
Remove warm baking sheet from the oven and add sunflower oil. Place the shrimp on the baking tray and bake for about 6 minutes, flipping the shrimp halfway through. Once cooked and crispy, plate the shrimp and enjoy!
