You don't often think about adding walnuts to dip, but why not? This blend is unusual enough to serve for a special gathering, and nutritious enough to serve the family as a snack. After all, you can't go wrong nutritionally speaking with yogurt, cheese, and nuts! Walnuts are also a relatively economical source of protein, with 1 ounce walnuts equivalent to 2 ounces of meat. Nutritious and yummy!
