Sage goes well with sweet potatoes.
More from Wikipedia:
As a herb, sage is considered to have a slight peppery flavor. In Western cooking, it is used for flavoring fatty meats (especially as a marinade), cheeses (Sage Derby),and some drinks. In the UK and Flanders, sage is used with onion for poultry or pork stuffing and also in sauces. In French cuisine, sage is used for cooking white meatand in vegetable soups. Germans often use it in sausage dishes, and sage forms the dominant flavoring in the English Lincolnshire sausage. Sage is also common in Italian cooking. Sage is sautéd in olive oil and butter until crisp, then plain or stuffed pasta is added (burro e salvia). In the Balkans and the Middle East, it is used when roasting mutton.
But yeah, sweet potatoes. Awesome.
