This is by far not all the wonderful food Spain has to offer, but some of those that I tried in my time in Madrid recently. I hope this helps your own foodie needs!
1. Paella (can be vegetarian)
A combination of rice, saffron, meat/fish, and vegetables.
2. Tortilla española
Made in a pan, this dish contains eggs, onions, and potatoes.
It’s not like tortillas in Mexico, but a solid mass that kind of resembles a cake.
3. Churros (con chocolate/with chocolate)
Basically fried dough, but delicious. S, see other posts, told me that it is usually eaten for breakfast or early morning after partying all night.
4. Tinto de verano
Red wine with coke or lemon soda (sprite/Fanta etc). Drank cold. Featured in the below picture of tapas.
5. Cerveza con limón
This is beer with lemon soda, in Germany/a brand is called Radler. Also drank cold.
There are many options for tapas. The biggest are with meat (different products from pig: con jamon y lacón). The only vegetarian options are basically potatoes, cheese, and bread.
Fried balls filled with potatoes or cheese, and meat. Featured in the picture above with the tapas.
Spicy sausage and some french fries in the picture below- part of a “racion” or ration/meal.
