I know this is an old thread but I love tahini and i love the hummus that Maria Emmerich makes on her blog (I'm not affiliated with her, I just love her no-grain low-carb recipes!!!) it's made with... Zucchini! and I even dip zucchini slices in it (overload, perhaps but it's YUMMY!):
zucchini hummusThat'll use up a bit of Tahini! (it's not a Thermomix recipe but I think it can easily be converted! I haven't made it since I had my thermie, must put it on my to-do list on the weekend!)
She even has a cinnamon "sugar" version on the same page (she uses natural sweeteners, you could definitely use sugar or rapadura in their place though that will change the nutritional value!)
