Sweat eggplant: Place eggplant in a colander set over a bowl. Sprinkle with salt, toss with hands. Leave for 30 minutes to sweat (no need to wipe off water that beads on surface).

Make tomato puree: Place tomato in a blender, food processor or other appliance of choice. Blitz until smooth. (No need to do this if using passata or crushed tomato.)

Cook eggplant: Heat 2 tbsp oil in a large skillet over medium high heat. Add eggplant and cook for 4 to 5 minutes, stirring regularly, until it's golden on the surface but still somewhat firm and raw inside. Transfer to a large pot.

Cook onion and garlic: In the same skillet, add another 1 tbsp olive oil. Add onion and garlic with a pinch of the salt. Cook for 3 minutes until onion is soft with a hint of golden on the edges. Add to pot holding eggplant.

Cook capsicum: Add another 1 tbsp of olive oil and cook the capsicum with a pinch of salt for 3 minutes. It should still be firm inside. You won't get much colour on the capsicum, this is OK. Add to pot.

Cook zucchini: Add another 1 tbsp olive oil and cook the zucchini with a pinch of salt for 3 minutes. Make sure it stays firm (ie. raw inside). Like the capsicum, it won't go golden. Add to pot.

Add remaining ingredients to pot: Turn the stove under the pot to medium-high. Add tomato, thyme, olives, remaining salt and all the pepper, and mix. Once the mixture is hot, reduce heat to a low simmer.

Braise: Cook for 20 - 25 minutes with the pot lid off, stirring every now and then, until all the vegetables are cooked through and the liquid has reduced. The mixture should be thick enough so you can pile it on a plate (ie. not watery), but still very moist and juicy.

Basil and salt: Taste and add more salt if needed; vegetables can taste bland if not enough salt is added. Stir through basil then serve immediately, drizzled with extra virgin olive oil and a sprinkle of extra basil on top, if desired. Serve as a main with crusty bread, or as a side dish.
