I’ve made a leg of lamb many times before, but when I learned how to make this at a course at George Brown Culinary, I fell in love with the simplicity of this recipe. Although cooking with a bone in has great advantages, a boneless roast can be stuffed, cooked and sliced to an elegant perfection.

Lamb is often considered a spring time feast and this recipe with it’s medley of veggies is perfect to grace your table at Easter or any other celebration. It’s center of Goat cheese gives the lamb a wonderful tenderness.
