If you look at the sample menus online at SW, they have it all chucked in the meal.
On the Extra Easy, day one's choice for evening meal is bolognese made with mince, onion, garlic, peppers, mushrooms and canned tomatos.
It doesn't say anything about having those superfree foods separately on the plate and there's no mention of having a side salad with it.
If it's good enough for SW, then it's good enough for me!
At the end of the day, it's using common sense when it comes to portion sizes. It won't kill anyone to serve up on a smaller plate or just have half the size of their normal portion. The food is free, so if you're still hungry afterwards (and I suggest waiting at least 20 minutes after your meal to give your brain chance to catch up with your stomach) then feel free to have more.
The point of SW is to eat until you're satisifed. That's how it works. If you're worried, then eat more fruit in the day or plan meals that can be portioned out like meat and veg.
