Salsa verde steak sandwiches from Taste and Tell are a satisfying Sunday supper. Thin slices of flank steak are paired with a homemade salsa verde and Monterey jack cheese in a hoagie roll. You can purchase salsa verde in a can but the flavors are far less superior then if you make it yourself. I like to add sauteed onions and peppers to my sandwich for an extra layer of flavor. Serve this sandwich with Mexican fries (French fries tossed in taco seasoning) and a margarita.
