Prepare the Spring Rolls:
Soak the rice paper wrappers in warm water for 10-15 seconds until pliable. Lay them on a flat surface.
Layer rice noodles, carrots, cucumber, red cabbage, mint, and cilantro in the center of each wrapper.
Fold in the sides and roll tightly. Serve with soy sauce or hoisin sauce for dipping.
Make the Dumplings:
Heat sesame oil in a pan over medium heat. Add mushrooms, cabbage, carrots, green onions, garlic, and soy sauce. Sauté until the vegetables are softened.
Place a small spoonful of the filling in the center of each dumpling wrapper. Fold and seal the edges with water.
Steam the dumplings in a bamboo or metal steamer for 8-10 minutes. Serve with soy sauce or chili oil.
Prepare the Tempura Batter:
In a bowl, whisk together the flour, cornstarch, baking powder, and cold sparkling water until smooth.
Fry the Tempura Vegetables:
Heat oil in a deep pan to 350°F (175°C). Dip the vegetables into the batter, allowing excess to drip off.
Fry the vegetables in batches until golden and crispy, about 2-3 minutes per side. Drain on paper towels.
Assemble the Platter:
Arrange the spring rolls, dumplings, and tempura vegetables on a large serving platter.
Add small bowls of dipping sauces (soy sauce, chili oil, hoisin sauce) for variety.
