Pineapple on pizza is a no no as quite simply, I hate pizza! A lovely tropical fruit with the life baked out of it, pineapple is best freshly cut up.
Agree with the eggs touching the beans being a no no but when it comes to tomato's in a fry up forget the tinned things warmed up on there own, sliced, fried tomato is best but the best part is the taste of the fried bread done straight after the tomato's!
