Cor denise...how long have you got?! LOL! There are soooo many things you can mix with pasta. The easiest sauce to make is simple tinned tomatoes and garlic, basil if you want some.
For an easy carbonara mix quark with eggs, fry a HE of bacon and stir through your pasta.
You can buy sauces but they will have syns. However, for ease, if you're prepared to syn it, things like pesto are quick and easy.
I wouldn't fancy the carbs overdoes with chips and pasta. But I love SW chips with baked beans and eggs. Yummmy! As for pasta, I like passata with onions and herbs and mushrooms and maybe some quark or fat free formage fraise stirred in. Also yum!
