Uses of leftover vegetables from slow cooker After slow cooking my pork over a bed of carrots, celery and onions. The pork gets eaten, the juice gets reduced to an amazing sauce base.

What can I do with the vegetables? They are tasty to eat as-is, but I want something a bit more creative?

Some idea (please chime in if you've tried something like this):
-puree the vegetables with the juice, then boil, reduce, mix in other ingredients for a heartier sauce
-use as toppings (pizza, burgers)

Also, with this in mind, are there other veggies I could add to the slow cooker? ie, adding veggies not just for how they flavor the meat, but adding veggies that will taste amazing after being cooked with meat for 12 hours.
My children love this kind of vegetables in a quiche (with some ham and olives as well).
