I use a weight watcher yogurt any 1 pp tub. Lots of frozen fruit 0pp then Rhibina light low sugar as much as required for thickness. I sometimes add chopped ripe banana. Made one the other day with frozen plums I had chopped and added some mixed spice it was yummy x all the smoothies are then only 1 pp
My fav is 200ml skimmed milk (2pp) 15g toasted porridge oats (1pp) and quarter or half a tin of apricots in own juice (0pp). Sometime I add half a banana to it aswell.
I toast my porridge underthe grill in batches so do three or four days worth in one
