We have pb&j, cereal (Cheerios and all bran - together-kids too
), or breakfast burritos most mornings.
We have a first morning snack of a muffin a lot of times (high protein muffin-ground up nuts in it)
We make a bunch of burritos and freeze them so we just pull them out and heat them up.
I have been known to make 4 or 5 days worth of scrambled eggs. They keep fine in the fridge.
