One of the few things in the Linda McCartney range that seems to have been phased out during the '90s, which is a great shame.
They were like chicken rissoles (though without the meat, of course) but had a cheesey-tomato topping, with the whole thing cooked in breadcrumbs.
When I became a veggie back in January '89, the McCartney range was one of the few vegetarian frozen options available, and I loved these- though only had them about twice before they seem to have been deleted for some reason.
