Heat a large skillet over medium heat. Add 1 tablespoon of olive oil.
Add the diced chicken breasts to the skillet. Season with salt, pepper, and half of the dried Italian herbs. Cook for about 7-8 minutes, stirring occasionally until the chicken is no longer pink in the center.
While the chicken is cooking, boil water in a separate pot. Add the tortellini and cook according to package instructions until al dente. Drain and set aside.
In the skillet with the chicken, add the remaining tablespoon of olive oil and the minced garlic. Sauté for about 1 minute until fragrant.
Add the cherry tomatoes, bell peppers, and zucchini to the skillet. Stir well and cook for an additional 5-6 minutes until the vegetables are tender but still crisp.
Pour in the balsamic vinegar and stir to combine. Add the cooked tortellini and toss everything together until evenly coated, allowing the balsamic to glaze the mixture.
Cook for an additional 2-3 minutes, ensuring everything is heated through. Adjust seasoning with more salt, pepper, or herbs if needed.
Serve hot, garnished with fresh basil if desired.
