Preheat the oven to 200C/400F/Gas 6.
Place all the vegetables and the garlic on an oven tray and drizzle with the olive oil and honey. Add the sprigs of rosemary and season well. Cook for about 20 minutes until all the vegetables are tender and browned.
While the vegetables are in the oven, cook the pasta according to packet instructions.
Remove vegetables from the oven, squeeze the cloves of roasted garlic over the vegetables and tip everything in a saucepan.
Add the passata, bring to the boil and allow to simmer gently for a minute or two.
Serve on top of the pasta and garnished with chopped rosemary.
The ratatouille can be made in advance and frozen. Then all you need to do is cook some pasta for a super speedy supper.
