Position an oven rack in the center and preheat oven to 350F degrees.
On an ungreased cookie sheet, toast the sesame seeds for about 10 minutes, or until golden.
Remove cookie sheet from the oven and immediately transfer the sesame seeds to a small plate.
In a large bowl mix the flours, sugar, baking powder and salt together and then sift to make sure that everything is well blended.
In another bowl, beat the egg and then add the olive oil and vanilla and beat until well blended.
Add the egg mixture to the flour mixture and stir and then knead by hand to make a smooth dough. (It will be slightly crumbly, but will hold together.)
Pinch of pieces of dough that are about a tablespoon in volume, and then roll them between your hands into fat little logs that are about 1-1/2 inches long and 3/4-inch thick.
Roll each log in the sesame seeds, tamping the ends in the seeds to finish them. Lay the cookie logs on the prepared baking sheet about inch apart.
Bake in the center of the oven for 30 minutes, until golden.
Remove from the oven and place the baking sheet on a rack to cool.
These cookies will keep well in a tightly closed tin.

In Sicily, such Biscotti di Regina are made with butter and white flour, but this version, with olive oil and part whole-wheat pastry flour, is just as delicious.This recipe can be easily doubled.
