Creating Crispy Bottom Veggie Buns is a gratifying experience. Here are the steps you’ll need to follow:

1. Prepare the Dough: In a large bowl, mix together the all-purpose flour, baking powder, and salt. Gradually add water and 1 tablespoon of vegetable oil until a soft dough forms. Knead for 5-7 minutes until smooth. Cover and let it rest for 15 minutes.

2. Prepare the Filling: In a skillet, heat a drizzle of oil over medium heat. Add minced garlic and ginger; sauté until fragrant. Then, add the mixed vegetables and cook for 5 minutes until softened.

3. Season the Filling: Stir in the soy sauce, sesame oil, chopped green onions, and black pepper. Cook for an additional 2-3 minutes. Remove from heat and let it cool.

4. Divide the Dough: Once rested, divide the dough into equal portions, approximately the size of a golf ball.

5. Roll Out the Dough: Take each portion and roll it out into a circle, about 4-5 inches in diameter.

6. Fill the Buns: Place 1-2 tablespoons of the cooled vegetable mixture in the center of each dough circle. Fold the edges over the filling and pinch to seal. Ensure there are no openings.

7. Prepare for Frying: Heat enough oil in a non-stick skillet over medium heat. You’ll want enough oil to cover the bottom of the skillet well.

8. Fry the Buns: Place the filled buns in the hot oil, ensuring not to overcrowd the pan. Fry for about 2-3 minutes on each side, or until golden brown and crispy.

9. Drain Excess Oil: Once cooked, transfer the buns to a paper towel-lined plate to absorb excess oil.

10. Keep Warm: Serve immediately while still warm and crispy. If necessary, keep them warm in an oven set to low.
