Love mangoes.
At Hungry Jacks, they have a mango thick shake, and it's yummy (forget about the fattening factor!).
$2, can't go wrong.
In the mornings, I can't stand to eat breakfast, until about an hour later, after my first cuppa coffee.
If I have to go out somewhere, then I take a banana and when the tummy rumbles, it does the trick.
I must have looked really uncool, eating a banana going into auto barn looking at reverse cameras for the hubby's vehicle

But honestly, what better brekky to grab and eat on the run except for a banana.
I love pears also.
Lemons are a fave, squeezed in water, makes a nice cleansing drink.
