Once I learned that on average a tablespoon of olive oil has about 120 calories, I started looking for other options for cooking and salad dressing, and I found Braggs. Now I use it in stirfrys, and on salads. Just drizzle it over your salad with some fresh lemon/lime and any fresh herbs/spice you like, and you will have created a 0 calorie salad dressing.
Braggs is all natural and has no preservatives. And again 0 calories!
