I'm curious as to what foods and desserts would be best suited to these
wines that we purchased in New Zealand some time back.

The Stoneleigh Marlborough Riesling (2004) has a fairly citrusy
character with a soft lime nose, and is slightly dry.
The Chardonnay from Hawke's Bay (2004) has a similarly citrus-based
character in the taste, but with a slight hint of melon as well. It's
also a little dry and fairly acidic.

What main courses and desserts would be best suited to these? I'm not
too much of a non-vegetarian (often eat chicken, but little else) - so
are there any specific vegetarian dishes and cheeses that should be
paired with these two wines (both for separate meals)?
