Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; drain.
In a small bowl roll beef strips in the taco seasoning until coated. In a large frypan over medium heat, warm olive oil. Saute beef and garlic until beef is no longer pink; about 4 minutes. Remove with a slotted spoon and set aside.
Mix together in frypan the cooked pasta, black beans, salsa and water; cook for 4 to 5 minutes. Combine with beef in a large bowl and serve sprinkled with coriander.
