Italian pasta recipes

i’m new to cooking for myself, and I particularly enjoy cooking pasta. what are some really tasty pasta recipes that you have all come across? i have a real taste for things such as olives and capers, by the way, so i don’t mind those at all.

any suggestions?
Fusili with Tuna Marinara:

Drain 1 can of Chunk-Light tuna in water, be sure to remove as much water as possible, then marinade it in about two tbsp of extra virgin olive oil, the juice of half a lemon (bottled juice will do if that’s all you’ve got) a pinch of salt, and a pinch of pepper

Best way to cook fish?

I’ve gotten pretty handy at cooking steak, poultry, and pork, but have never tried cooking fish.

I have a pair of Mahi steaks I plan on cooking tomorrow – pointers? Recipe suggestions? Anything I should know about cooking fish that’s different from cooking dry land meats?
depends very much on the fish (I am no expert either, but based on my successes/failures).

first off, don’t keep it long or its going to get funky–i tend to cook it the day i buy it. likewise for leftovers–don’t plan on having any.
