Mix ground turkey with breadcrumbs, egg, and half the parmesan; roll into 20 meatballs.
Bring a large pot of salted water to boil, add pasta, cook 10 minutes until al dente.
While pasta cooks, brown meatballs in a skillet over medium-high heat for 8 minutes, then add marinara sauce.
Drain pasta, toss with meatballs and sauce, top with remaining parmesan and serve.
