You don't have to follow SW recipes to follow the plan. Muller lights are completely optional, no idea why people go on about them so much.
Just cook normal food like cooked breakfast, omelettes, baked potatoes, cottage pie, curries, soups, tray bakes (eg fish or chicken, vegetables, potatoes), roast dinner, paella, stir fries, spaghetti bolognaise, pasta in a tomato, olive and tuna sauce, etc etc making sure you follow the rules about including plenty of veg, use an oil spray, lean meat etc.
It's not even necessary to follow it that closely. It's just a calorie reduction plan without the need to restrict or weigh and measure most things except bread and obvious junk like cake, crisps, takeaways, biscuits etc.
It worked for me even when I used full fat cottage cheese, Greek yogurt and a bit more cheese than allowed. The main benefit comes from eating hardly any high calorie treats like alcohol, crisps, cake, chocolate etc.
