Subway restaurants offer a variety of submarine sandwiches, wraps and salads, promoting themselves as a healthier alternative to traditional fast food.

What you choose on your sandwich can significantly affect its nutritional value, including the sweet onion sauce. The serving size for the sweet onion sauce is 1.5 tbsp., according to Subway. However, the actual amount of the sauce on your sandwich or wrap varies depending on how it is prepared.
