Bacon option; place a halved cooked bacon rasher on top of heated beans and continue layering as above. Note

You could use tahini (sesame seed paste) instead of grinding the toasted sesame seeds. Beans or watercress can be used instead of spinach in this salad, and peanuts or macadamia nuts could be substituted for the sesame seeds. If you like, you can sprinkle the cooked spinach with smoked dried bonito flakes. Note

Any kind of dried beans can be substituted for canned beans, if preferred. Soak beans overnight. Boil until tender; drain. Use patience when spreading polenta into prepared pan; it tends to move and slip but can eventually be worked into corners of pan. Polenta can be made 1 day ahead to the refrigeration stage. Note

Instant mash is a dried mashed potato mix reconstituted with boiling liquid to give a light buttery flavour. It is available from most supermarkets. Note
