We don't eat a heck of a lot of pasta either and I don't really know why as we both enjoy it. Anyhow, we have two favourites:
The one I do most often involves passata, chopped bacon or lardons, red onion, chilli and a good glug of balsamic. We usually have that with penne, we're going to have it tomorrow evening.
The other one, which we havent had in ages but which I used to make regularly
has mushrooms, thinly sliced courgettes, strips of ham or fried bacon, and creme fraiche, with loads of Parmesan stirred through. We have that with farfalle. Looking up the recipe has reminded me how nice it is so I'm going to make it next week.
I can't abide warm tuna, tuna pasta bake is the devils work. Can't say your aubergine one floats my boat either Eccles, was it nice?
