DH is vegetarian since the horse meat thing. I'm not but it's hard to cook separate meals all the time so today made vegetarian bolognese and it's FAR nicer than my usual.
I used red lentils instead of meat...onions finely chopped, garlic, fresh and dried basil, rosemary tomato, passata and some finely diced carrot and celery as well as a teeny spoon of marmite.
It's SO nice and obviously cheaper too!
