Toaster strudels (wilberry is not only super good, but has the cool blue frosting packs lol), fruit, breakfast sandwiches that you can microwave, good old classic cereal, yougurt, toast (with butter, jelly, peanut butter, or cinnamon), donuts. Of course not everything, lol but take your pick of a few of those. And serve with juice.
why not make a lovely fruit platter. you can make some really nice designs with the fruit and then have little pots of yoghurt or spiced cream fresh to dip the fruit in. you could also do fruit kebabs and put the fruit on skewers.
