"A traditional Ulster fry consists of bacon, eggs, sausages (either pork or beef), the farl form of soda bread (the farl split in half crossways to expose the inner bread and then fried with the exposed side down), potato bread and tomatoes. Other common components include mushrooms, wheaten bread or pancakes. All this is traditionally fried in lard."
Here's one version of it.http://www.mrbreakfast.com/superdisplay.asp?recipeid=727
* 2 Bacons
* 2 Sausages
* 1 Vegetable Roll (sausage meat mixed with scallions (spring onions))
* 2 Tomatoes
* 4 Mushrooms
* 2 Eggs
* 1 Soda Farl (the flat version of soda bread)
* 2 Potato Farls (Irish potato bread)
To that you can also add white pudding, black pudding, onions, friend pancakes and fried bread.
For myself, I'd go with the bacon, sausage, vegetable roll, mushrooms, white pudding, and onions, all fried.
