Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Dice the eggplant, zucchini, and red bell pepper into uniform half-inch cubes.
Toss the diced vegetables on the baking sheet with 0.5 tablespoons of olive oil and a pinch of sea salt.
Roast the vegetables for 20 minutes, or until they are tender and slightly caramelized at the edges.
While the vegetables roast, slice the chicken breast into bite-sized strips and season with salt and pepper.
Heat the remaining 0.5 tablespoons of olive oil in a large skillet over medium-high heat.
Sauté the chicken for 5-7 minutes until golden brown and cooked through, then remove from the pan and set aside.
In the same skillet, add the diced onion and minced garlic, sautéing for 3 minutes until translucent.
Pour in the crushed tomatoes, dried thyme, and dried oregano, simmering the sauce for 5 minutes.
Stir the roasted vegetables and cooked chicken into the tomato sauce and garnish with fresh chopped basil before serving.
