One can can easily serve four or five people -- and those are people who *like* haggis and want a real portion.

I guess there is such a thing as too much of a good thing...! :-)

One serving suggestion -- breakfast haggis! I eat it more often for breakfast than with dinner. It's amazing served with scrambled eggs. Add a bit of HP brown sauce for added tang if desired. For a really huge breakfast add a serving of Heinze baked beans, and a few slices of tomato and/or mushroom. mmmmmm......
