In a large bowl, mix flour, salt, and warm water to form a soft dough. Knead until smooth. Cover and rest for 30 minutes.
Prepare the filling by heating oil in a pan. Add tofu, carrots, zucchini, and green onions. Stir in soy sauce, sesame oil, and black pepper. Cook until fragrant.
Divide dough into equal portions and roll each into a ball. Flatten and roll out into small rounds.
Place filling in the center of each round. Fold edges over and pinch to seal. Flatten gently.
Heat oil in a skillet over medium heat. Cook each pancake until golden brown on both sides.
Serve warm, ideally with a dipping sauce like soy vinegar or chili oil.
