What is the most popular food in Spain as a national dish common to Spanish homes?

Spain has many regions and each region has it's own favorite dishes. Spaniards as a group eat lots of potatoes, garbanzos, rice, fish, chicken and fresh fruits and vegetables. In fact, almost all fruits and vegetables are purchased fresh. Sausages, cheeses, and cured meats are also very popular.

However, due to the extremely varied regions there is no single dish representative of all Spain with one exception. Bread is eaten universally at most meals.
