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.

Gently mix in noodles, tuna, peas, and half the cheese, keeping noodles intact.

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

Bake 25 minutes until hot and lightly browned. Rest five minutes.
