You could have an egg (make an omelet or boil them the ways to cook eggs are endless!) on toast or a low fat cheese and tomato ( I love this with a bit of mayo and onion flakes) sandwich. Baked beans on toast are nice too.
Personally I love cereal and I usually have weetbix (they aren't the best tasting but they are easily portion controlled! and are nice with a bit of 2 fruits or tinned peaches on top)
Try to add a piece of fruit (in season I love to have an orange)
Make sure you are getting enough calcium with yoghurt (natural is best) or cheese.
