Arugula
Arugula is a dark and leafy green vegetable with a hint of a peppery flavor. Arugula is a common ingredient in salads and is rich in vitamin K and provides just a few calories along with calcium, potassium, and folate. One half cup which is almost 10 grams of arugula has only three calories, which is quite amazing as it gives a satiating feeling too without almost no calories.
