For a more laid back approach to lasagna, this recipe can be broken down into two days of cooking. Cook the sauce and prep the chicken on day one. Make the béchamel and build the lasagna on day two. Use a rotisserie chicken from your local grocery store to make the cooking process a bit easier. Depending on how cheesy you prefer lasagna, feel free to add more parmesan and fontina cheese. Be sure to evenly distribute all components of the lasagna.
