Yup, can deffo get vegetarian haggis. Not tried it, but mum bought it by accident, much to all of our amusement. I miss all the Scottish (and some not so scottish!) things we used to have at my nana and papas - fried fruit pudding, square sausage, butchers links, black pudding, fried leftover potatoes, tablet (it simply isn't the same down here), Barr lemonade in glass bottles, haggis, mince and tatties, and ANYTHING in a floured bap. I swerved the deep fried pizza though......
Not having a Scottish supper myself, but hope you all enjoy yours! Your pie MLM brings back memories of black pudding potato croquettes I made once - super yum!
