Combine spices (ground black pepper, salt, ginger) and vegetable oil in a bowl.

Rub the spice mixture onto the chicken breast.

Cover the chicken and marinate in the refrigerator for at least 30 minutes.

Heat vegetable oil in a pan over medium-high heat.

Add the marinated chicken to the pan and cook for about 10 minutes, or until almost cooked through.

Add the chopped green pepper, red pepper, yellow pepper, onions, and white mushrooms to the pan.

Cook until the vegetables are tender-crisp (al dente).

Stir in the soy sauce.

Warm tortillas or pita bread.

Prepare the avocado sauce by mixing avocado, mayonnaise, lemon juice, salt, and oregano.

Spread the avocado sauce on the tortillas.

Add the chicken and vegetable mixture on top of the avocado sauce.

Sprinkle mozzarella cheese over the chicken and vegetables.

Roll up the tortillas and serve immediately while the cheese is melted.
