Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the chicken breast into thin strips and dice the eggplant, zucchini, and red bell pepper into uniform half-inch pieces.
In a large mixing bowl, whisk together the tomato puree, extra virgin olive oil, minced garlic, herbes de Provence, sea salt, and black pepper.
Add the chicken and chopped vegetables to the bowl and toss thoroughly until every piece is evenly coated with the herb-tomato mixture.
Spread the mixture in a single layer onto the prepared baking sheet, ensuring the pieces are not overcrowded to allow for proper roasting.
Roast for 25 to 30 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized at the edges.
Remove from the oven and garnish with freshly chopped basil before serving warm.
