Pasty and mushy peas is decent.
Pea and ham soup is great (dunno if its strictly British).
Black peas are great.
But WAIT, I do actually like other things besides peas.
Chicken is great, roast etc. Steak and peppercorn sauce. The only British foods I dont like are hotpot and Potato Hash cos I don't like onions.
Fry up/Full English is good after a big night out too.
Crumpets are good too, especially with some of that Italian cheese thing you can get now, sprinkled on top. Its like cheese powder in a tube. Very nice.
Broth and dumplings is great too. Even though I don't like onions I eat them in that because its all so good.
My cousin and I used to eat brown/red sauce butties...I dunno why. Just to annoy my mum I spose, cos she hates sauces.
