Heat the oven to 375°F. Cook the noodles until just tender, then drain them.

Stir the soup, milk, garlic powder, salt, and pepper in a large bowl.

Add the noodles, tuna, peas, and half the cheese. Mix gently so the noodles stay intact.

Spoon everything into a greased baking dish. Top with the remaining cheese and breadcrumbs mixed with melted butter.

Bake for 25 minutes, until hot and lightly browned. Let it sit for five minutes before serving so nobody burns their tongue in a hurry.
