Irish bubble and squeak.
- About 2 lbs floury potatoes
- 1 head of kale, finely chopped (or cabbage if you can't get kale)
- Chopped scallions (spring onions)
- Salt and pepper
My gran always simmered the kale in the water discarded from boiling a ham/bacon and indeed some colcannon recipes call for diced ham to be added.
my Irish grandmother did it exactly the same way (with the bacon water).
