Preheat the oven to 400°F (200°C).

In a large pot, bring salted water to a boil and cook the tortellini according to package instructions until al dente.

In a mixing bowl, combine heavy cream, mozzarella cheese, Parmesan cheese, garlic powder, onion powder, salt, and pepper.

Once the tortellini is cooked, drain and return to the pot. Add broccoli, cherry tomatoes, bell pepper, and the sauce mixture. Stir to combine.

Spread the tortellini and vegetable mixture evenly on a sheet pan.

In a small bowl, mix panko breadcrumbs with olive oil and Parmesan cheese, then sprinkle over the top of the tortellini mixture.

Bake in the preheated oven for 20-25 minutes, or until the top is golden and crispy.

Remove from the oven and let cool for a few minutes before serving.
