Heat a small nonstick skillet with the olive oil and cook the corn, stirring, for 5 minutes. Add 1 tablespoon of water if the pan gets dry. Add the spices and hot red pepper sauce. Set aside.
In a medium nonstick skillet, place 1 tortilla on the bottom. Evenly distribute the corn mixture, tuna, scallions, and cheese on the tortilla. Place the second tortilla on top and cook until golden on the bottom, 2 to 3 minutes. Turn the quesadilla over and cook until golden on the other side, 2 to 3 minutes more, or until the cheese melts. Cut into 6 wedges.
