Crack the eggs into a bowl, add the sugar and pepper, and beat well.
Cut each slice of bacon into 4 small pieces.
Heat a frying pan over medium-low heat and cook the bacon on both sides until it starts to brown.
Pour the beaten eggs into the pan with the bacon. Add the shredded cheese and gently stir over low heat in large circles to let the eggs form big, soft curds.
Warm each tortilla in the microwave for about 30 seconds. If the tortillas feel dry or stiff, sprinkle a little water on them before microwaving to make them softer.
Divide the scrambled eggs and bacon among the 3 tortillas, then wrap them up.
Optionally, grill the wrapped tacos in a frying pan until the tortillas are lightly golden and crispy.
