Breakfast or Lunch

Breakfast or Lunch
I very often have Marmite for breakfast and Peanut Butter for Lunch (or supper occasionally). So when Mat and Emma gave me a jar of Marmite and Crunchy Peanut Butter for my birthday you can imagine my dilemma.
'Breakfast or Lunch' ? 
Anyway I gave it a go for breakfast today and jolly nice too. I will have to try it for lunch now sometime (or supper).
