We do our different kind of fruits/veggies and protein then add our cereal alternative just as a filler. Some we dont do anymore but I threw them in for ideas for you
Pancakes
muffins
bagels
toast
tortillas (corn and flour)
sweet rice
sweet bread from a baker
cream of wheat
sweetened polenta
granola
biscuits
bread pudding
french toast
waffles
banana bread
croissants
pita bread
thats all I can think of right now but the above can be added to breakfast in all kind of ways.
I do have to admit, I still buy kashi cereal even though I know there are tons of ways to fix breakfast without it
I think perhaps Ill stop, now that I just typed out all the alternatives
Eta: oh ya, potatos. hashbrowns, potato cakes, fried potatos in olive oil.
Also popcorn cereal is pretty yummy! You just air pop corn and add in things like shredded coconut, raisins, nuts, things like that.
