Trader Joe's has a very decent "multi-grain" pancake/waffle mix. I went from serving my boys totally white flour pancakes to this mix and they didn't bat an eyelash.
That said, we have recently abandoned healthy/grainy pancakes and are totally loving Buttermilk Griddle Cakes from the Fannie Farmer/Boston School of Cooking cookbook. They are so good and fluffy and tangy and just as a pancake should be! But they won't win any awards in the health category. I have toyed with the thought of tossing some flax seeds or something like that in there to feel like a better mom. But I just never seem to go buy the flax seeds.
good luck.
