This festive main course consists of three dishes that go together perfectly: Chicken roulades, Hasselback sweet potatoes and a green asparagus salad. In this recipe, Mathijs demonstrates how to produce your own chicken roulades with garlic, lime and sage. (You could also buy them from your poulterer.) By cutting the sweet potatoes into fans, they will bake more quickly. The green asparagus is eaten raw as part of a salad. Here's a recipe sure to delight everyone.
