Spread 11 oz - 300 gr of cherry tomatoes, 2 roughly chopped red peppers and 1 courgette halved and cut into slices in an even layer on some parchment paper on a baking tray, drizzled with olive oil and plenty of salt and pepper.
Roast for 30 minutes until soft.
Now make the risotto
Mix together 1 c - 250 ml of passata and stock with 1 T - 15 ml of balsamic vinegar in a large measuring cup.
Now to start your risotto, heat the remainder of the olive oil in a medium-sized saucepan on a medium-low heat. Add the 4 finely chopped shallots and cloves of garlic and stir until they have become translucent.
Add 11 oz - 225 gr of arborio rice, and keep stirring continuously from here on out. Stirring releases the starches in the rice and is the absolute key to a good creamy risotto.
Once your rice is coated in olive oil and has started to go translucent, this should take 5 minutes or so, start adding your passata - stock mixture, one ladle at a time. You should not add more liquid until the previous ladle has been fully absorbed into the rice.
After 20 minutes or so, your rice should be soft and all the liquids should have been. You can now add 6 chopped sun-dried tomatoes and the pre-roast veg. Stir everything in gently so the vegetables hold together a little bit. Taste and add more salt and pepper if necessary.
Serve with fresh basil and lots of freshly ground black pepper.
Notes
Once cooled down, reheated risotto is not very nice unless you roll it into balls, coat it in breadcrumbs and deep-fry it.
