Any quick and easy breakfast ideas for fussy eaters?

It kind of depends on what type of food your child prefers. If he/she likes cold food, overnight oats is easy to make, or sandwiches (like with ham and cheese, or egg mayo perhaps?) are some good options. If he prefers something crunchy/chewy, toasting some bread for the crunch factor and simply need to spread some peanut butter or jam (depending on whether he/she prefers sweet or savory food) or if there's time, fry an egg for the sandwich. French toast is a quick and easy (and tasty) option as well. Personally, I think some crackers topped with cottage cheese and some sliced fruits makes for a quick and simple breakfast as well. But my personal go-to would be overnight oats. :)
