It's beginning to look a lot like summer, and this citrus avocado salad is the perfect treat to get you ready for the warmer days to come. Low- calorie, light, but with satisfying flavors. Grapefruit, avocado and pineapple are beneficial for someone who is watching their weight. Grapefruit is also good because it clears up skin. I really enjoy eating avocado and pineapple because avocado helps control appetite while pineapple boosts energy!
