To make peeling tomatoes easier, put them in a small pot of boiling water and let stand while you chop up the other vegetables
Wash and cut up the vegetables.
Heat 3 tablespoons of olive oil in a heavy-bottomed pot. Add cubed eggplant to the pan, and cook over medium heat, stirring frequently, until golden. Add a bit more oil if the eggplant absorbs all the oil and sticks to the bottom of the pan. Remove the eggplant when done and set aside.
In the same pot, pour in 2 more tablespoons olive oil. Add onions and cook for about 7 minutes, or until soft and translucent. Add the garlic, dried chile flakes, and a bit more salt.
Cook for 2 or 3 minutes, then stir in yellow pepper. Cook for a few more minutes, then stir in zucchini. Cook for a few more minutes.
Peel and chop the tomatoes, disolve tomato paste in a half a cup of water and add both to pan.
Add the Herbes de Provence mix then stir in eggplant and cook for 10 to 15 minutes more, until all the vegetables are soft. Adjust the seasoning with salt.
Drizzle more extra virgin olive oil to taste and serve.
