About half the time, cereal for breakfast, as follows:
Microwaved oatmeal, topped with a few spoonfuls of wheat germ. Over this I pour low-fat plain, unsweetened kefir, the very sour kind (Lifeway). If I am out of kefir, I use buttermilk. (No rolling of the eyes, please.

)
Sometimes, for variety, I use shredded wheat (unsweetened, of course

) instead of oatmeal/wheat germ. With that, I usually opt for buttermilk instead of kefir.
Sometimes--I say this on the grounds that confession is good for the soul

-- I have a slice of homemade cornbread (the type with no sugar on it), baked ahead of time and frozen, to be microwaved for breakfast. Over the cornbread, I pour buttermilk. (It's an old Southern dish, one I remember from childhood, although even then no one would have had it for breakfast.

Very good, however.)
Yes, I am not joking. This is all very good.
Occasionally I add fresh blueberries if I have them.
On rare occasions I have corn flakes (eek! all that sugar!) with a banana, but when I do, I have that for a light evening meal, not for breakfast.
It's a free world. . . .
