In a medium bowl, combine the mustard, canola oil, honey, cumin, and chili powder. In a rectangular pan, arrange the chops so they are in one layer, pour the marinade over the chops, cover with plastic wrap and refrigerate. Allow the meat to marinate at least one hour and up to 6 hours, turning the meat over at least once.

In a large bowl or rectangular glass dish, drizzle the eggplant slices with extra virgin olive oil and sprinkle with the cumin and herbes de Provence. Season with salt and pepper.

When ready to grill, prepare a charcoal or wood fire and allow it to burn down to ashes, or preheat a broiler if cooking indoors. Place the eggplant rounds on the grill and cook 1 to 2 minutes on each side, until slightly charred and tender. Remove from the grill and reseason with salt and pepper. (This may also be done on the stovetop, with a Teflon-coated grill pan.)

Season the lamb chops with salt and pepper and place on the grill. Grill chops for 4 to 5 minutes on each side or until medium rare. (This may also be done in the broiler.)

To serve, place the eggplant slices on a large platter, overlapping in an oval. Place the lamb chops over the eggplant. To serve on individual plates, place 2 slices of eggplant on each plate and top with two lamb chops.
