Jean-Marc has a good idea to check the eroski site for information -- I´d go there first for all of your routes, kiwi-family. Based on my own recollection, here are a couple of random memories from the Salvador-Primitivo, not in order (and of course this is a moving target since things are always changing):
-- Pajares -- microwave and a few pots-dishes, I think
--Pola de Gordon -- microwave and absolutely nothing else
-- monastery in Cornellana (microwave but not much else)
-- San Juan de Villapanada (full kitchen, hospitalero cooks communal dinner with pilgrims)
--Bodenaya (same as San Juan, you do not have access to the kitchen except as a helper)
-- Pola de Allande, not even a cracked cup
--Berducedo - some basic supplies
--Grandas de Salime -- full glorious kitchen
--Fonsagrada-Padron -- full kitchen
-- Cadavo -- pretty full kitchen
-- San Roman --small municipal albergue has well stocked kitchen
-- Lugo - kitchen with nothing in it
-- Melide -- municipal albergue has full stocked kitchen, as does Arzua.
I´m sure there are more, but these are the ones that I remember. Good to hear from you again, mamakiwi! Laurie
