Ds and I are doing SW and my cooking skills have dramatically improved over the last year and I'm pretty confident now.
We use a slimming site called "slimming eats" which is amazing and has meals that are "free" on the plan or very low fat.
This one I made last night and took 15 ish minutes. It's called pizza chicken.
Take 2 ( per person ) chicken breasts and put in a ziplock bag and flatten a bit with a tenderiser or a hammer 
Season with sea salt and cracked black pepper and cook on hob for 2 minutes on each side.
Use a mixture of 300ml passata, dried oregano,basil, garlic and a bit of purée and mix in a bowl and then cover the chicken with it, like a pizza base.
Add cheese of choice, we used mozzarella but also use cheddar.
Can also put extra toppings on such as mushrooms/onions/peppers/sweet corn etc.
Oven proof dish and in oven for 12-15 minutes and done.
Served with jacket potatoes ( micro ones ) and salad of choice.
We really enjoyed it and will be making this one again soon.
