2. 1 green pepper
3. 1 medium tomato, halved and thinly sliced into half-moons
4. 1 yellow bell pepper, thinly sliced
5. 1 orange bell pepper, thinly sliced
6. 1 red bell pepper, thinly sliced
7. 1/2 red onion, thinly sliced
8. extra-virgin olive oil spray
9. 1 tsp. Italian seasoning: basil and granulated garlic
10. Kosher salt
11. Freshly ground black pepper
12. 1 cup shredded mozzarella

Make slits in each chicken breast, being careful not to cut through completely, and stuff with vegetables.

Bake until chicken is cooked through and no longer pink inside, 45 minutes.
