For me, its a bowl of cereal, usually grape nuts or cheerios. Sometimes with blueberries. Quick and easy.
Also, weird fact;
I put table cream or half and half in my cereal. My grandmother grew up on a dairy farm on PEI and when they were kids the best cream was always used by her family for cereal or tea. Well, she had 6 kids, who then had 13 more and all of us use cream like weirdos (and drink lots of tea). And no, we are not all obese because of it, everything in moderation. =)
^ I may or may not be eating grape nuts and cream right now.
