Hi There,how about cooking the rolls in chicken stock til tender and serving
this as a side sauce,I think the pears would complment the sweet potatoe
filling nicely......see what you think.

PEAR SAUCE
*************
2 ripe pears,peeled,cored and chopped
2 Tbls cream or thin yogurt
1/2 tsp chilli sauce (or to taste)
pinch ground netmeg

Place evrything in a food processer and blend til smooth.Transfer to a small
pan and reheat gently til warm.......

Hope you like the idea
Love Julie
