Hello!
I have a gluten allergy and walked from SJPP to SdC both of the last two falls (and will again this fall) without any significant food issues. Because albergues that include breakfasts in the fee, I am rarely able to eat what is offered unless fruit, juice, and/or tea are available, and because many places do not include breakfast regardless, I am in the habit of carrying a tin of tuna, fruit, and nuts in my pack. Also, as mentioned earlier, many cafés offer tortillas (egg and potato). Just make clear that you don't want any bread on the plate. For the pilgrim meals, the menus almost always include gluten-free options, e.g., ensalada mixta for the first course, meat/fish and potatoes or rice for the second, and fruit for dessert. Communal meals can be a little trickier. But I found that most hospitalieros want to make sure that there is something for me to eat and ensure I receive double servings of salad or other items if the main course includes gluten. Sharing those meals with other pilgrims is worth any lost calories that might result from not eating everything offered. As long as you carry a few things in your pack and are willing to be flexible about what gluten-free food you will eat, you will have a full belly along the way.
Buen Camino!
