Blitz the first 3 ingredients in a food processor or chop really finely with a sharp knife, mixing the oil in when done.
Season well with salt & black pepper.
Cook your chop/breast/fillet under a grill or in a frying pan until almost done.
Spread generously with the garlic and walnut paste. Cover in breadcrumbs and grill for a few minutes until the breadcrumbs are golden brown and the meat/fish is fully cooked.
