I keep meaning to make a low-syn version of the yummy M&S pasta, spinach and pine nuts salad, but so far haven't got round to it. Anyway, this is what I'll do when I do make it:
Cooked pasta
8 squirts of Filippo Berio olive oil spray (2 syns)
Raw spinach chopped up a bit
1teaspoon of jarred pesto (about 1-1.5 syns)
1 level tablespoon pine nuts
Cherry tomatoes are nice, if you have some. Could probably also add chopped red or orange pepper, yum!
If you prefer your pine nuts toasted, they can be cooked off in fry light, then basically just mix all the above things together - can probably be done without the olive oil spray, but it does help the small amount of pesto to go further - even if I weren't making a low syn version, I'd just add olive oil to the pesto rather than using more pesto; of course, you could use a tablespoon of extra virgin olive oil as a healthy extra B instead of using the spray.
The M&S version also has grated cheese in, which could be added as a HEa.
