Heat up oil in a large skillet over medium heat. Add the turkey and cook for a minute or two while breaking it up with a wooden spatula. Add the diced onions and continue to cook for another minute.
Add the minced garlic, orzo, salt, and pepper. Stir for 30 seconds.
Add the broth and passata sauce to the skillet. Stir in the Italian seasoning.
Bring the skillet to a boil and simmer for 8 minutes, stirring frequently.
Add the frozen peas and parmesan to the skillet.
Stir until well combined, and the peas are cooked through. If the sauce is not thick enough, simmer for a little longer or add more parmesan.
Top with more parmesan before serving, if desired.
