Yeah, so I made Welsh onion cake which is essentially potato, butter, onions, more potato, more butter and probably more butter again. This was really easy to veganise since the only thing I really needed to change was the butter, using vegan margarine instead. I had to have a lie down after this, think I had some kind of carb brown-out.
100g melted vegan margarine
500g onions, I used a mix of spring, white and chives but the original recipe calls for just white
2 rosemary sprigs
1kg of maris piper potatoes, peeled and thinly sliced
Salt and pepper to taste
Use about the quarter of the marge to saute the onions and rosemary in a frying pan for about 15 minutes whilst the oven is warming up.
When they're ready remove from the heat and discard the rosemary sprigs.
Thinly slice the potatoes and put about half of them in a dish. Pour half the remaining marge over these, then spread the onions over the top. Add the remaining potatoes then cover that with the last of the marge. Sprinkle with salt and pepper.
Roast with a lid on for about 40 mins, then remove the lid to brown the top layer for another 20 mins or so.
Traditionally you would turn this over to serve but fork that noise, I am way too messy to do stuff like that and not have it fall apart.
