A couple weeks ago I decided to make Rice Krispy treats using brown crisp rice. Um, you should also too. Holy cow! SO GOOD! I'm not sure exactly how great a benefit you're getting by using brown crisp rice over regular krispies, but I know they taste good. And the ones I use (Barbara's) are organic, so hey, there's a plus. Additionally, I add 1/4 C. milled flax seed to the marshmallows and stir it in right before adding the crisp rice. I think it gives it a nice nutty taste and really does add nutrition!
Chrysta, you were asking about homemade granola cereal that's healthy also too. Maybe take a look at this recipe (there are tons of recipes on that site. I'm a SLAVE to that site.)? I'm not an expert on health. Maybe Kelly (health guru extraordinaire and good friend) will chime in.
