Bring a large pot of salted water to a boil. Add the linguini and cook until al dente.
Meanwhile, heat heat some oil over medium heat in a large frying pan. Add the garlic and anchovies, and saute for 2-3 minutes. Crush the anchovies with the back of a wooden spoon.
In a small bowl, mix together the hot water and crushed tomatoes, then add the anchovy mixture.
In a medium frying pan, heat some oil over medium heat. Toast the breadcrumbs, and season with salt and pepper.
Drain the pasta and mix with the sauce and half of the breadcrumbs until fully combined. Divide into bowls and top with the remaining breadcrumbs.
