Preheat the oven to 350°F. Line a baking sheet with baking paper.
In a large bowl, mix together all the ingredients to make a smooth dough.
Divide the dough into 10 balls and roll each ball into 4 inch long stick. Place them on the prepared baking sheet.
Brush the grissini with extra olive oil and sprinkle with extra sesame seeds.
Bake for 12- 15 minutes or until they are just starting to turn golden.
Remove from the oven and allow to cool completely before serving.
