Bake or microwave the potatoes until almost cooked. Cut the partially
cooked potatoes length-wise into 4 wedges each (total of eight).
In a bowl mix together the mustard, olive oil, thyme, salt, and
pepper. Coat the wedges with the mustard mix.
Preheat a grill
to medium heat and lightly oil the grill surface.
Add the potatoes and cover the grill. Check every 5 minutes,
turning the wedges to brown on all sides. Cook 10 to 15 minutes
or until
crispy.
