Reddit reviews Three Generations of Chilean Cuisine

If you want to go all in, here's a link to the cookbook my Chilean grandma used and gave to me.

If you don't want to get a whole cookbook, for a party, I would make chorrillana (fries with steak, caramelized onions and fried eggs - delicious! Recipe here), avocado and celery salad (chopped avocado and celery dressed with olive oil and lemon juice) or Chilean salad (chopped tomatoes and onions dressed with olive oil and lemon juice), alfajores for dessert, and pisco sours (because I like cocktails more than wine, personally). Empanadas de pino are very traditional and a big feature at all of my family events, but more time consuming to make than the dishes above.

Also, if you can find Chilean or Argentinian chorizo and marraqueta bread, grilled choripan sandwiches are my favorite asado food.
