You can if you're using version 0.99.6 (see below) or the latest SVN 
tree.  Check out the -T fields option along with the -e <field name> 
option and optionally the -E field in the man page.

For example:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

sfisher@shadow:/usr/local/src/wireshark>./tshark -R "http.request.method 
== GET" -r ~/captures/http.pcap -T fields -e http.host -e 
http.request.uri -E headers=y

sfisher@shadow:/usr/local/src/wireshark>./tshark -R "http.request.method 
== GET" -r ~/captures/http.pcap -T fields -e http.host -e 
http.request.uri -E header=y

http.host       http.request.uri
