Strawberries, Peaches, and Tangerines. Strawberries are very Low in carbs (< 1g/Strawberry)...Peaches and Tangerines are also relatively Low in carbs.

Apples (even small ones) are much higher in carbs, but they are low-glycemic. So, I have them occassionally. I also have an occassional piece of Watermelon or Cantaloupe, despite their high glycemic index. I'll also eat orange slices when they come with an entree.
