This recipe is nearly verbatim from the back of the pinhead oats bag:
In a large pot bring water to a boil and add oats, salt and pepper-reduce to a simmer, cover and cook for 2 hours.
Add meat, onion, spices and cover, cooking for 1 hour more.
Pour into pan/s-cool and then refrigerate.
Turn out, slice and fry until brown in a bit of butter or oil.
