Have just picked up a Nutri Ninja Slim, and am having heaps of fun combining different vegies and fruits in it. The mango/spinach/vanilla yoghurt was sublime, but I don't know that I'll be trying the broccoli/strawberry combo again. I'm going to give this a try as a meal replacement (breakfasts primarily) and also perhaps as an afternoon snack before flute teaching or zumba. I'm mostly going to be going the veggie versions, to try to minimise the amount of sugar I get in my diet (which is horrendously high... I am a sugar junkie). Anybody else make their own smoothies, and what machine do you use?
