Our leader was talking about this on Monday night, evidently the prepacked stir fry veggies have chemicals on them to preserve them and this is what causes them to have points, if you want a truly 0 point veg stir fry unfortunately you will need to buy the fresh veg separately and prepare yourself. Its the same for the prepared asparagus. The less prepared the veg the better.
You could try some slices of chicken or pork, or prawns or for a veggie option quorn (really low in points).
