I was doing my routine shop and saw some roast potatoes and almost bought them. Then suddenly I saw it marked out as "NOT SUITABLE FOR VEGETARIANS" So I looked at the ingredients and it said it contained BEEF drippings
So don't automatically assume simple vegtables are even halal, double check. If it wasn't marked out on the front, I would've bought them :(
Ingredients
Potato, Vegetable Oil (11%) (Corn Oil, Sunflower Oil), Beef Dripping (6%), Salt
