Preheat oven to 450 degrees.

Using a sharp knife, make slits 1 inch deep all over the lamb. Insert the garlic. In a small bowl, combine the mint and rosemary. Rub the lamb with the olive oil and the herb mixture.

Place the lamb on a rack in a roasting pan and roast for 30 minutes. Reduce the heat to 350 degrees and continue to roast until an instant meat thermometer placed in the thickest part of the meat, away from the bone, registers 135 degrees for rare or 140 degrees, about another 45 minutes.

To make Sweet Mint Sauce: In a food processor or blender, place the mint, oil, vinegar, water, garlic, and sugar substitute. Process until smooth. Add the pepper and salt. Set aside until ready to serve.

To serve, slice thin slices of lamb and top each serving with 2 teaspoons of the mint sauce.
