Bran cereal has never been a favorite of mine. I've only recently started eating it because it's got the magic "f" word (fiber). Unfortunately, after two months straight of eating it every morning, it gets a little bland. I found a quick fix up - my personal cinnamon toast blend.
1 to 1-1/2 teaspoon Splenda, 1/2 teaspoon nutmeg, 1/2 teaspoon cinnamon. I sprinkle it over my cereal and it really, really livens the cereal up.
Of course, once it starts cooling down, I'm going to switch to oatmeal, but it's a good quick substitute.
