You'd probably be healthier and less hungry if you spread a tablespoon or two of natural apple butter between two slices of 100% whole wheat bread and eat that instead of those over-processed diet "meal bars". And I heartily second the recommendation of little dabs of peanut butter on an apple (or a pear)- yummy!!
There are some really DELICIOUS rice blends with wild and brown rices available- so nutty, flavorful and chewy and wonderful compared to nutrition-stripped white rice. Lots of fiber and nutrition there. You can make up a pot and divide it into several servings ahead of time.
