Pre-heat the oven to 160’C
Fry the onions and the sausages in a deep casserole dish (I use a le creuset) until the sausage is golden brown.
Add the rest of the vegetables and the garlic and regularly stir for about 5 minutes.
Add the rest of the ingredients (except the corn flour) and bring to the boil.
Place in the oven and cook for 1-2 hours. The longer the better as it turns really rich and tender.
Remove from the oven and if the sauce hasn’t thickened then mix the corn flour with either a little water or a little milk and stir into the casserole.
Return to the oven for another ten minutes and when ready serve with mash potato or seasonal greens, I fried some curly kale in a bit of garlic and butter and it was delish.
