If you are ever on the west side of Houston and want to try some Argentinian cuisine stop by Marini's Empanada House on Westheimer just a bit east of the Sam Houston Tollway. They have a Katy location as well.
Essentially an empanada is a fried or baked hand pie that can be stuffed with meats, vegetables, cheeses or desert options. Marini's has over 40 combinations on their menu. They even allow personalization where you describe what to put in the empanada.
