cactus fruit

Someone told me that these bite sized bits were edible. . .
So, true to my childlike spirit of adventure, I had to try one.
(the one that's missing)
It was yellow. . .
But no, it didn't taste like lemon and actually it was pretty bitter.
I don't imagine the orange one would taste like orange or the red one like cherry either.
I guess if you were castaway on a desert island with nothing else to eat, you'd thank God for these nasty little bite size bits.
But when you know you've got leftover pizza back home in
the fridge. . .
