I also have a cuisinart 14 cup and I use it pretty often. I crank out half dozen or more pie crusts, wrap them in discs and keep them in the freezer for when I need a crust or two. I make small batches of bread in there (so if I need just one loaf it's easier than hand kneading and my kids getting into something while I'm up to my elbows in dough). I love the slicing attachment for scalloped potatoes even if it did nothing else. I also whiz up the nonmeat ingredients of my meatloaf in there (and I make huge batches of meatloaf) until it's a paste and I mix that paste into the meat. Biscuits or any kind of short dough are a breeze in the food processor especially when you're wanting to use well chilled butter. Hummus of course, any other dips and sometimes pesto though most times I'll make pesto in the vitamix.
I don't use it for soups, etc. since I have an immersion blender and I prefer to just stick it in the pot since I make double and triple portions.
