Spaghetti with pesto and roast tomatoes

I'm on a bit of pesto kick at the moment. The local greengrocer is full of fat bunches of basil and there's no other way to use one up before it goes off even if you add basil to everything. Not that making pesto is a hardship. It's so bright and flavourful and vivid in flavour - light years away from the drab, almost khaki-coloured paste you get in jars.

Since I posted the recipe on my student site beyondbakedbeans.com we've been having it slathered over everything which is why there wasn't quite enough to make the sauce I devised for our pasta lunch today (Napolina spaghetti being on special offer in Somerfield at the moment at 2 packs for £1.50). And why it looks slightly duller than it should. (I had to add a dollop of Sacla green pesto to stretch it)

Anyway it's a nice recipe potentially for you other pesto addicts out there . . .

Serves 2
225g spaghetti or linguini
2 tbsp olive oil
150g cherry tomatoes
1 tsp chopped fresh oregano (optional)
2 good dollops homemade green pesto (find the recipe here)
Salt and freshly ground black pepper
A little shaved or grated parmesan

Put a large pan of water on to boil, add salt and cook the spaghetti or linguini following the instructions on the pack. While the pasta is cooking heat the oil in a frying pan and add the tomatoes. Cook over a medium heat, shaking the pan occasionally until the tomatoes are soft and beginning to char. Chuck in the oregano if you have some. Drain the pasta reserving a little of the cooking water then return to the pan. Spoon in the oil you used for cooking the tomatoes then add the pesto and a couple of spoonfuls of cooking water and toss well together. Tip the pasta into warm bowls, top with the roasted tomatoes and shave or grate over a little parmesan.

What am I going to do with the rest of the Sacla pesto that's now sitting accusingly in the fridge? Mix it with breadcrumbs and make a topping for fish. Add it to sandwiches. Stir it into a soup. Possibly zip it up with some more fresh basil - although I'd rather use any new basil for a fresh batch of homemade pesto. Any other ideas?
