Remember when salads were a bit, well, sad? There was only one sort people went for, and we were never really inventive with our choices. And then along came spinach, a type of leaf, dark green in colour, that changed the salad game forever. As it turns out, spinach is one of the most versatile vegetables out there. It can be eaten raw or cooked, blended or chopped, canned, frozen, added to pies, pizzas, pasta dishes and sandwiches, and it’s even now considered a smoothie staple.
