Feeling blue? Try some blueberries from Costco - a five pound bag is just under $11 - making the superfood that is very heart healthy about $2. 09 a pound and so yummy. Makenzy loves eating them - though messy - they stain her hands and about everything else they get on. We like to make our own fruit smoothies - a layer of fat free vanilla yogurt, a handful of granola cereal and blueberries on top! You know us - economical and yumma!
