Place pork, lime zest, garlic, TABASCO® Sauce and cumin in a 5-quart Dutch oven; add water to barely cover. Bring to a boil; reduce heat to low, cover and cook 2 1/2 hours or until water has evaporated. Add salt and continue cooking pork in its own juices until browned, stirring occasionally. Remove lime zest and garlic; drain off excess fat and adjust seasonings.
Place tortillas in a zip-top plastic bag and microwave on high for 1 minute. Carefully open bag, allowing steam to escape, and remove tortillas; wrap in a kitchen towel to keep warm.
To serve, place some cooked pork in the center of each tortilla; add pico de gallo, then fold both sides of tortilla to cover filling.
