Preheat your oven to 400°F (200°C).
On a large baking sheet, toss the cubed eggplant, zucchini, and red bell pepper with 0.5 tablespoon of extra virgin olive oil, sea salt, and black pepper.
Roast the vegetables for 20 minutes until they are tender and slightly caramelized around the edges.
While the vegetables roast, heat the remaining 0.5 tablespoon of olive oil in a large deep skillet over medium heat.
Add the diced yellow onion and sauté for 4 minutes until translucent, then stir in the minced garlic and cubed chicken breast.
Cook the chicken for 6-8 minutes until browned on all sides and cooked through.
Pour in the tomato puree and dried oregano, then reduce the heat and simmer the sauce for 10 minutes to allow the flavors to meld.
Gently fold the roasted vegetables into the skillet with the chicken and sauce, heating for another 2 minutes.
Remove from heat and garnish with the chopped fresh basil and thyme leaves before serving hot.
