Have you tried the different savoury tofus? DD is addicted to the sate one, cut up in fingers served cold. Great taste, preservative free and full of protein. There are 4 in a pack for $4. Pitted olives, cold sweet corn (raw or cooked), cold cooked potatoes from the night before, cold boiled eggs (also cooled in advance) are other favourites here. Also couscous salad cold with a few veggies, herbs or cheese in it is quick and easy.
