A few pasta dishes are vegan until it comes to the cheese on top at the end. I'm thinking of the Sicilian dish pasta alla Norma, which has a delicious tomato and aubergine sauce. You'd normally sprinkle some salted ricotta (ricotta salata) on top, but often in Sicily they would replace the expensive cheese with toasted breadcrumbs on pasta dishes. I haven't tried that on that dish but it could work. It works on pasta con la sarde well enough.
