Diet protein rich "not really cheesecake".
Sandwich two corn (or rice) cakes with hazelnut chocolate spread. Soak and dissolve over heat 1tsp agar agar, in 50ml of water (could use gelatine or cornflour as an alternative), mix in a tbsp of honey and strawberry conserve (or sweeteners of choice, to taste). Remove from the heat, and stir in 100g of fromage frais (yoghurt, including low fat, would work, but not as well). Select a pastry cutter of similar size to the corn cake, and balance on the base. Pour the fromage frais mixture into the cutter. Refrigerate for around half an hour. When set to the touch, run a knife around the cutter to release, and push off.
I don't like desserts enough to piss about much, or waste calorie allowance on super sweet or pastry based stuff, but this can be made out of store cupboard ingredients in ten minutes work, plus setting time.
