Last year I visited Spain for the first time for about a week and a half. I have been a strict vegetarian/vegan for over 15 yrs. I was thrown off guard when my first meal that was ordered for me was a tortilla (as you know, basically, an omlette). I ate the eggs much to my dismay only to be polite, but really wished I hadn't. I found a local grocery store and found the one bag of frozen veggies they had and some pre-cooked brown rice. Each morning I had a pastry for breakfast, rice and veggies for lunch including salad stuff I bought and potato salad and olives for dinner most nights. It was light, simple and delicious. The fresh fruits and veggies were very cheap and tasty. Even though I got by with the food just fine, I loved Spain and can't wait to return. The people were so friendly and I was happy to get back to my cultural roots. I wish the best in your time there. Enjoy every minute of it...
