In a large saucepan, shallow fry the sausages, garlic, rosemary and the chilli in the olive oil for approximately 1 minute.
Add the carrots and celery and fry for a further 3 minutes.
Add the borlotti and cannellini beans and season with salt.
Add 400ml of boiling water, cover with a lid and leave to simmer on a low heat for 20 minutes.
Remove the lid- take out the sausages and cut into three pieces.
Place back in the casserole with the cherry tomatoes and carry on cooking without the lid on a low heat for another 10 minutes allowing the sauce to thicken.
For the garlic bread
In the meantime slice the bread approx. 2cm thick.
Brush with extra virgin olive oil and place on a hot griddle until both sides are crusty.
Once ready, rub the garlic over the warm bread.
To serve
Serve the garlic bread immediately with the casserole.
