What can I substitute for dairy products in kosher meat dishes?
In the Israeli Army I've had a veal "parmesan" made with a tahini sauce. It's a very different dish, of course. It's also common to get beef/noodle recipes that don't include the dairy component.

In general you're often better off substituting the meat (for fish, or a vegetarian patty like seitan) or working off of different recipes. Trying to make kosher cheeseburgers (and putting margarine on the shabbat table) are the hallmarks of the newly religious.
