MUSTARDS' YAMS

Steps:

• Cover yams with salted water and boil until tender, so that a fork will penetrate easily. Run them under cold water immediately.
• Cut yams in half-inch slices lengthwise.
• Mix together oil, tamari, ginger and scallion and pour over potatoes.
• Mix together the ingredients for the vinaigrette and reserve.
• Put yams on the grill for a minute, then turn them 90 degrees and cook for another minute to burn a cross-hatch pattern into them. Turn over and repeat process.
• Remove to a platter and drizzle vinaigrette over all.
