Spaghetti Bolognese

I'll admit that I'm lazy and usually make a quick spag bol using sauce from a jar and it's usually ready in about 20 minutes. I thought I'd try this as I'm trying to be healthier. If I do it again I'd do it on a weekend and not midweek as there was quite a bit of prep to do and as I am just cooking for two it seemed a bit of a faff. I tasted the sauce as I was going along and as it was a bit bland I added balsamic vinegar and tomato purée, which helped and didn't add any points. I'm not sure if it was really worth making this recipe over using a "light" jarred Bolognese sauce, but it was edible and filling and tasted okay with the aforementioned adjustments.
