I have wrapped uncooked diced lamb in thin filo pastry to bake in the oven ... how long and at what temp?

I have wrapped uncooked diced lamb in thin filo pastry to bake in the oven, it also has some cheese, veggies and a bit of mustard... How low should the temperature be and for how long should I cook it so that the filo doesn't burn, but the lamb cooks properly?
