is this possible? our van dont have an oven?

I quite often do mine in a saucepan on the top of the stove Milo.  Depends on the recipe I would imagine but if all the ingredients are put in together then I don't see why it wouldn't work for you.   If you want my recipe let me know.

Please put it in the What's Cooking site Ma.
