I am a serious mango lover! You could try frozen mangos cubed (but only a couple of cubes, as they are not super low carb). If you have no self control with moderation (like me) try buying a few fruit flavored syrups (SF of course) I make flavored Soy Slender milk all the time- or those yummy, rich Italian Sodas- just mix some seltzer water , syrup, adn top with a bit of cream (Soy slender works for this too if you avoid dairy)
These syrups also make a great add in to cream cheese or Peanut butter - I have made this kind of mixture & enjoyed it on an LC tortilla or a Cheeters cracker.
Hope this helps you get some ideas!
