What is salad oil if it being used in a no yeast bread stick recipe?

Salad oil is not used in a no-yeast breadstick recipe. Yeast, or baking powder or baking soda, is what causes the bread to rise and give it a light, fluffy texture. Salad oil is used to grease baking sheets and pans, and occasionally lightly coat doughs to prevent sticking, but is not an ingredient in breadsticks.
