20 minutesMelt the butter in a saucepan over a medium heat. Add the flour and stir to form a roux. Cook for 1 minute. Slowly add the beer while whisking, then cook until the sauce has thickened. Add the grated cheese and mustard and whisk until melted. Season to taste.
Place the waffles on a baking tray and top with the ham, Swiss chard and cheese sauce. Grill until golden brown.
Cook's note: The buttery, cheesy goodness of traditional Welsh rarebit meets the spongy sweetness of ready-made waffles this quick - sticks Sunday supper mash-up. Use nonalcoholic beer if you like.
