We also occasionally do weetabix which is devoured extremely quickly, you can mix in nice small chunks of fruit with it
Weetabix with a range of different fruits mashed in, yoghurt with mashed banana and peanut butter, cheese on toast, crumpets with butter and jam. You could try the egg alternative and see how it comes out for pancakes or french toast I think tesco sell it now
My eldest had an egg allergy. Some of his faves, lots of which have been said already, but also fruit crumbles, egg free pancakes, yoghurt and toppings, cereals, homemade baked beans on toast
We do a lot of what you've already said but we've recently alos tried oat bars which have been a winner and crumpets which are hit and miss!
