Mortadella?

[monahue]

Iam a total novice cook but I do like to try, so I bought Nigella's Kitchen. In the first recipe she uses mortadella. WHen I went to Sainsbos tonight the only mortadella I could find was sliced in the cooked meat section. Is that what she means or do I need something else?
I realise that this is a totally boneheaded question but the frittata looks yum and I want to get it right!

nothing helpful to say other than you reminded me that as kids we called it 'death sausage'

I don't know the recipe, but chunks of mortadella might be better, but if you can only get it in slices then that will do. Do they not have a hunk of it that you could ask them to cut one thick slice from?
