Emptying the shopping bags

Ok, so I mostly don't get the horror of the supermarket shop, but I do get the job of emptying all those bloody Bags. Do we really need/eat all this stuff? Apparently we do.
Rarely do I feel like a proper cook after this - just too much food - and the exercise usually involves finding stuff hidden in the back of the fridge that has to be eaten now!
So there was a less than a portion of roasted vegetables, and half a tin of tomatoes that demanded attention. And a pack of shop made (Tesco Finest) cannelloni stuffed with ricotta and spinach. They all seemed destined for each other.
The left-overs were bunged in a saucepan with a glug of mushroom ketchup, a splash of balsamic vinegar and attacked with the hand held blender until pureed. A handful of chopped purple basil (again nearing the end of life) and parsley perked the whole thing up. Voila, instant sauce to cover the pasta which went into a dish into a hot oven for 25 minutes. Oh, and a grate of cheese on top.
Not half bad too it turned out. I have done the stuff your tubes with cheesy spinach mix: comparing effort to result the shop ones came out on top. The sauce, well a happy happen chance of leftovers.
