Tortas are hot, and Mexico's Deli on Dairy Ashford has the best tortas in Houston. That's because the proprietor once owned a popular chain of torta stands in Mexico City — he relocated to Houston when the peso bit the dust. Mexico's Deli offers more than 20 variations on the Mexican sandwich, plus some blackboard specials. The torta lomito Argentino, a steak and egg sandwich, is among the best. It features a thin slice of beef tenderloin, a fried egg, a thin slice of ham, mozzarella, avocado and tomato, all on a huge bun spread with refried black beans. The torta al pastor is made with marinated pork and bits of pineapple carved from a trompo (a cone of meat on a vertical roaster) on display beside the grill. Don't miss the flan for dessert — it's made with a pecan praline in the baking cup underneath the custard, for a simple but delicious twist on the old favorite.
