So far - only walnuts.
I should not have said, "only".
Walnuts are REALLY good for us:
As a dog-owner, I feel, I must add a note here:
Walnuts and Macadamia nuts are NOT good FOR our DOGS.
Sesame seeds - both in its original form and in Tahini. Tahini is useful to have on hand. I use it in some cookies, as well as the obvious hummus. I've used it as my "fat source" in vegetable loaves. It's delicious AND healthy.
