Skirlie is a Scottish oatmeal dish that's usually made as a side dish for stovies or stew, as a stuffing, or stirred through mashed potatoes to give them a bit of crunch. It's also not a bad way to cook oatmeal for breakfast (as is regular savoury porridge by the way), but like the Scots themselves it's a bit dour on its own, so you'll need to add some flavourings.

Traditionally it's made with dripping or lard, onions and oats (not rolled though - you need pinhead or medium/fine oatmeal), but you can make it with butter, oil, or even shredded suet if you're using it as stuffing (in which case you may not need to fry it up first).
Personally I find the version made with pinhead oats a bit too crunchy to eat as a stand-alone dish, so I cook some stock into it to soften it at the end.

A Savoury Porridge
side veg
Quite a decent breakfast if you add enough flavouring.
If all you have is rolled oats you could make the same dish but without bothering with frying the oats - just add water (or stock) and cook them as for porridge.
A savoury porridge. Without the sugar.

Serves 2 for breakfast, or 4 as a side dish

In a heavy frying pan heat the fat and soften the finely chopped onion without browning them overmuch.
Add the oatmeal, season with salt and a generous pepper grinding, and stir to coat thoroughly.
You could add chopped bacon or chorizo with the oatmeal.
Cook over a very low heat, stirring frequently, until the oats soften and taste a little toasty (about 10 minutes for medium, 20 for pinhead).
You might throw in some sliced garlic and then roughly chopped tomatoes towards the end.
If you find the oats too crunchy add some stock (water and a little oxo cube also works) and turn up the heat to cook off the liquid until the oats reach the texture you'd like.
With a grating of cheese, some chopped herbs, a fried egg or even a dollop of crème fraîche for a tasty savoury porridge breakfast.
