As my husband
@jungleboy said above, you definitely won't need to bring your own stove, as many albergues have kitchen facilities. Some vegetarians and vegans do prefer to cook their own meals, but we mostly ate our dinners in restaurants or albergues and just ate picnics for lunch (fresh bread, avocados, tomatoes, the occasional tub of hummus, etc.).
A surprising number of communal meals in albergues are vegetarian by default anyway. Or maybe it's not that surprising, since avoiding causing unnecessary harm to sentient beings is definitely in line with the spirit of the Camino. ;-)
In any case, even if the default meal is not vegetarian they can usually make a vegetarian/vegan version. I can only think of one albergue that said they were not able to do this for us. Some of those communal meals were really delicious!
Here is a list of some albergues (and a few restaurants) that offer veg options:
La Vita è Bella in St Jean Pied de Port
Albergue Maribel in Cizur Menor
La Perla Negra in Azqueta
Parochial hostel in San Juan de Ortega
Albergue San Bruno in Moratinos
Cuatro Cantones in Belorado
Orion in Castrojeriz
San Antonio de Padua in Villar de Mazarife
Albergue Verde in Hospital de Orbigo
Casa Las Aguedas in Murias de Rechivaldo
Monte Irago in Foncebadón
El Trasgu de Foncebadón
Albergue de Ada in Reliegos
La Siesta (food truck) in Camponaraya
Alea in Ponferrada
La P’tit Pause (restaurant) in Villafranca del Bierzo
El Serbal y La Luna in Pieros
Miriam Las Herrerías in Las Herrerías
Project Brigid in Las Herrerías
El Refugio in La Faba
El Beso in A Balsa
Molino de Marzán at A Leda
Casa Domingo in Ponte Campana
Ultreia in Arzúa
This list is not exhaustive, but it will get you started. Eventually, I hope to create a more extensive resource for vegetarians and vegans on the Camino. In the meantime, check out my article "6 Tips for Eating Vegan on the

Buen Camino!
