You are wrong: 
(all tests done on a fresh sid chroot): 

pt-get install nagios3
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following extra packages will be installed:
  apache2 apache2-mpm-worker apache2-utils apache2.2-bin apache2.2-common
  bind9-host bsd-mailx dnsutils exim4 exim4-base exim4-config
  exim4-daemon-light file fping libapr1 libaprutil1 libaprutil1-dbd-mysql
  libaprutil1-ldap libbind9-50 libdb4.5 libdns50 libexpat1 libfreetype6
  libgd2-noxpm libgssapi-krb5-2 libicu40 libisc50 libisccc50 libisccfg50
  libjpeg62 libk5crypto3 libkeyutils1 libkrb5-3 libkrb5support0 libldap-2.4-2
  liblockfile1 liblwres50 libmagic1 libmysqlclient15off libnet-snmp-perl
  libpcre3 libperl5.10 libpng12-0 libpq5 libradius1 libradiusclient-ng2
  libsensors3 libsnmp-base libsnmp15 libsqlite3-0 libsysfs2 libtalloc1
  libwbclient0 libxml2 makedev mime-support mysql-common nagios-images
  nagios-plugins nagios-plugins-basic nagios-plugins-standard nagios3-common
  nagios3-doc openssl openssl-blacklist psmisc python python-minimal python2.5
  python2.5-minimal qstat radiusclient1 samba-common sgml-base smbclient snmp
  ssl-cert ucf xml-core

Hm this are not that much... but: 
apt-get -o 'APT::Install-Recommends=false' install nagios3

The following packages were automatically installed and are no longer required:
  libgomp1
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:
  apache2-utils bsd-mailx exim4 exim4-base exim4-config exim4-daemon-light
  libapr1 libaprutil1 libexpat1 libfreetype6 libgd2-noxpm libjpeg62
  liblockfile1 libpcre3 libperl5.10 libpng12-0 nagios-plugins-basic

Huh? much smaller. And indeed looking into the depends field of nagios3 reveals: 
(nagios3) 
libc6 (>= 2.3.4), libgd2-noxpm (>= 2.0.36~rc1~dfsg) | libgd2-xpm (>= 2.0.36~rc1~dfsg), libjpeg62, libperl5.10 (>= 5.10.0), libpng12-0 (>= 1.2.13-4), zlib1g (>= 1:1.1.4), nagios3-common (= 3.0.6-4), perl
(nagios3-common):
Depends: nagios-plugins-basic, nagios3-doc, coreutils (>= 4.5.3), bsd-mailx | mailx, adduser, lsb-base (>= 3.0-3), ucf (>= 0.28), apache2-utils, debconf (>= 0.5) | debconf-2.0

There is nothing I could remove there. Ok maybe nagios-plugins-basic or nagios3-doc, but most people really don't want this. 

So you can disable installation of recommends, but there is nothing I can do
for you.
