Preheat a large non-stick skillet over medium-high heat and coat with cooking spray.
Add the ham and cook, covered, for about 2 minutes, stirring once or twice, until the ham is hot and beginning to brown.
Reduce the heat to medium-low and pour the egg substitute over the ham. Without stirring, cook 3-4 minutes until the eggs are partially set. Stirring gently in order to scramble, continue cooking for 1-2 minutes until the eggs are nearly set.
Sprinkle the cheese over the eggs and cook, stirring gently, for 1 minute until the eggs are cooked but not dry and the cheese is melted.
While the eggs cook, warm the tortillas according to the package instructions.
Arrange the warm tortillas on a flat surface. Place one quarter of the egg mixture along the right side of each tortilla, stopping shortly before the bottom. If desired, top the eggs with Picante Sauce.
Fold up the bottom edge of the tortilla (about 1 inch).
Beginning at the right edge, roll each tortilla up jellyroll style. Serve hot.
