I think they generally do (eg including onions & spinach in rice, onions & tomatoes in curry/bol mixes etc etc) but tbh I think you have to use your own judgment. eg fish & chips is never going to be SF-friendly and they'll hide a photo of a pile of salad in the corner or something. 1/3 of your plate needs to be superfree fruit & veg, If you think the recipe has that in already, great, if it doesnt you need some on the side.
