Preheat oven to 425°F and line a large sheet pan with parchment paper.
In a small bowl, combine 2 tablespoons olive oil, Italian seasoning, rosemary, minced garlic, salt, and pepper.
Toss the halved baby potatoes with 1 tablespoon olive oil and spread them on one side of the sheet pan. Roast for 10 minutes to give them a head start.
While potatoes are roasting, rub the turkey cutlets with half of the herb mixture, making sure both sides are well coated.
Remove the pan from the oven and add the turkey cutlets. Arrange cherry tomatoes and zucchini slices around the turkey and potatoes, then drizzle vegetables with the remaining herb mixture.
Return to the oven and roast for 15-18 minutes, or until turkey reaches an internal temperature of 165°F and vegetables are tender.
Squeeze fresh lemon juice over everything and garnish with torn basil leaves before serving. Perfect over pasta or with crusty bread!
