What is the best way to freshen up one bowl of cold cereal?

Ain't no way, just eat it fast and forget it.

there is NO way to freshen it up. Your cereal will be all yucky, i.e. soft and mushy instead of crisp and gorgeous.

The best way is to make another bowl of cereal

I'd pour off all liquid from the bowl, and then add

ice cold milk to it.

Fresh fruit, berries, nuts... Depending on the cereal, you could use almond milk, or even chocolate milk.

Almond Soy milk.

Put some sliced fruit or a hand full of berries on top.

Add a little more dry cereal, and eat it fast.

Add Fruit.

Add condensed milk to this. It will become more tasty

:)

Use chocolate milk instead.
