When I did slimming world I would make ice cream from Quark by stiring in a sachet of Options hot chocolate powder, some granulated sweetener and then putting in the freezer. Took about 3 hours to freeze to a kind of soft ice cream (would stir every 30 mins or so)
I also used to make a chicken kiev with it. I would slice a chicken breast and then mash some Quark up with garlic and stuff it in the middle. I'd use a tooth pick to hold it close. Then I would brush with mixed egg and roll the chicken breast in some smash. Not made up smash, literally in the dry flakes. This would then bake in to a kind of crunchy coating around the chicken. Not exactly like breadcrumbs but still nice.
I'm just starting on Alli today but will be checking out the fat content in these lol.
