Preheat your oven to 375°F (190°C) and grease a 9x13-inch casserole dish with cooking spray or a light coating of olive oil.
Bring a large pot of salted water to a boil. Cook the orzo pasta according to package instructions until al dente, then drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the diced onion, carrot, and red bell pepper. Cook for 5-7 minutes or until the vegetables are softened.
Stir in the diced zucchini and minced garlic. Cook for an additional 2-3 minutes until the zucchini is tender and the garlic is fragrant.
Add the canned diced tomatoes (with juices) and vegetable broth to the skillet. Stir to combine and bring the mixture to a simmer.
Stir in the chopped spinach and cook for 2-3 minutes until wilted. Season the mixture with salt and black pepper.
Remove the skillet from heat and fold in the drained orzo pasta, Parmesan cheese, and half of the shredded mozzarella cheese.
Transfer the mixture to the prepared casserole dish, spreading it out evenly.
In a small bowl, combine the breadcrumbs, melted butter, and chopped parsley. Sprinkle this mixture evenly over the top of the casserole.
Sprinkle the remaining shredded mozzarella cheese over the breadcrumb topping.
Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.
Remove from the oven and let rest for 5 minutes before serving.
