Bring a large pot of lightly salted water to a boil. Cook pasta at a boil, stirring occasionally, until tender yet firm to the bite, about 10 minutes. Drain, rinse gently, and drain again.
While pasta boils, toss zucchini, bell peppers, carrot, green onions, and tomato with olive oil in a large bowl.
Combine balsamic vinaigrette and honey in a small saucepan and bring to a boil. Lower heat and simmer until it coats the back of a spoon, 8 to 10 minutes.
Add pasta and balsamic reduction to the bowl of vegetables and toss gently. Season with salt and oregano; toss. Adjust seasonings as needed.
