My daughter is allergic to nuts. What could I use in place of pine nuts in pesto?

Bulgur is a quick-cooking form of whole wheat that has been cleaned, parboiled, dried, ground into particles and sifted into distinct sizes. Bulgur is a nutritious, versatile wheat product with a pleasant, nut-like flavor and an extended shelf-life that allows it to be stored for long periods. This would make a perfect replacement for pine nuts in your pesto. You can find bulgur at most grocery stores or specialty stores.
