Place the sun-dried tomatoes in a cup of warm water
to soak for about 15 minutes, or until softened. Remove,
coarsely chop, reserve the soaking water, and set aside.
Heat 3 tablespoons of olive oil in a large wide pot over
medium heat and cook the onion and garlic until wilted,
about 8 minutes, stirring.
Add the cauliflower pieces, toss to coat in the oil, and add
the plum tomatoes and tomato paste. Add the red wine, bring
to a simmer, and add the bay leaves, cinnamon, and orange
zest. Add the sun-dried tomatoes.
Taste the soaking liquid and if it isn’t too salty, add that to the pot as well. Season lightly with salt and pepper.
Cover and simmer over low heat for about 25 minutes, or until the cauliflower is tender but still al dente. Add the olives and continue cooking for 5 minutes. Remove and serve, sprinkled with chopped fresh parsley and a little extra olive oil if desired, for garnish.
