I experimented in the kitchen today. I really like the cheese and onion bread from Morrisons, so tried to make my own. Using a white bread mix, I followed the instructions, but also added grated cheese and finely chopped onion to the dough. Once the dough was risen I sprinkled the top with a little grated cheese and onion. Tiz a little close textured, but quite tasty.
I'm sorry, I haven't taken a picture of it.
