This is a simple and nourishing autumn dinner, easy to prepare after work and a great way to use the ubiquitous Swiss chard that arrives with the changing of the leaves. Bake until golden and bring a little autumn sunshine into your evening!
Preheat oven to 400°F (200°C). Wash and dry each stalk of Swiss chard. Remove the ends of Swiss chard stalks if dirty and then chop each stalk into thirds. Arrange Swiss chard in a large baking dish. Pour béchamel sauce over the Swiss chard. Top with grated Gruyèr
