Mmm, cheese and Marmite? Try it – it works really well!
(If you are not in the UK, find another yeast-based spread.)
You need to make sure that the baguette is warm when you assemble it, so it is best to make your own bread or buy one of those part-baked ones which are readily available in supermarkets.
2-3 tablespoons Marmite
50g grated cheese (I used cheddar)
Cook the baguette according to instructions.
Cut in half and slice down the middle of each half.
Spread with Marmite.
Then cover with the grated cheese.
Serve on its own or with a green salad.
