In a small bowl, combine sugar, eggs, vanilla and oil. In a larger bowl, sift flour, baking powder, salt and chocolate chips.
Pour wet ingredients into dry ingredients and stir until solid dough forms (if pressed for time, I'll use my hands in a pinch. As long as they're clean it will save you time and frustration - the dough gets sticky).
Shape dough onto a baking sheet into a 13 x 3 log. I like to lightly spray the baking sheet, as sometimes the biscotti has a tendency to get stuck to the sheet if you forget (which I have and often do).
Bake for 30 minutes and remove from oven when biscotti is beginning to turn golden brown. Cool for approximately 10 minutes and reduce oven temperature to 300F. Before replacing in oven, slice diagonally into thin pieces. Arrange sideways on a baking sheet and bake for approx. 10 more minutes, or until biscotti is baked through and edges are golden brown.
