I have Mozart's Turkish March and Tchaikovsky's Russian Dance from the Nutcracker Suite... both are a bit hard at the moment, although, I love them both.
Take a look to Bernhard posts, there´s one of them with a list of pieces you may enjoy.
Let me guess, it's the section of the Alla Turca with the octaves in the right hand and rolls in the left, right?
There are movements in that sonata that are beautiful, have you tried them? My favorites are variations III, IV and V. I always hear about people playing the Alla Turca, and nobody playing the rest of the sonata. It's a shame...
