Ingredients

Sourdough Buns

  • 500 g wheat flour
  • 150 g rye flour
  • 120 g active sourdough starter
  • 380 ml warm water
  • 10 g salt
  • 1 tbsp olive oil
  • Sesame and black sesame seeds for topping

Tofu Marinade & Filling

  • 400 g natural tofu
  • 2 tbsp soy sauce
  • 1 tbsp olive oil
  • 1 tsp honey
  • 1 garlic clove minced
  • 1 tsp sesame seeds

Burger Filling

  • 1 avocado
  • 150 g mushrooms sliced
  • 1 small onion sliced
  • ½ cucumber sliced
  • 2 spring onions sliced
  • Chinese cabbage leaves
  • Salt and pepper to taste

Instructions

  • Mix the wheat flour, rye flour, sourdough starter, water, salt and olive oil into a dough. Knead until smooth, cover and let ferment slowly for about 24 hours.
  • Divide the dough into 8 small burger buns. Let them rest briefly, sprinkle with sesame seeds and bake at 200°C until golden.
  • Slice the tofu into thick pieces. Mix soy sauce, olive oil, honey, garlic and sesame seeds, then marinate the tofu for at least 2 hours.
  • Sear the tofu in a hot pan until golden and slightly crispy on both sides.
  • Lightly sauté the mushrooms and onions until soft and lightly caramelized.
  • Mash the avocado with a little salt, pepper and lemon juice if desired.
  • Slice the buns, spread avocado on the bottom half and layer with cucumber, tofu, mushrooms, spring onions and Chinese cabbage.
  • Serve immediately while the tofu stays crisp and warm.

Notes

Keep It Plant-Based: If tofu is not your favorite, grilled tempeh, roasted mushrooms or a bean-based patty also work well while keeping the burger fully plant-based and satisfying.
Make It Lighter: Serve the burger with a large crunchy salad or raw vegetables instead of fries. The extra fiber, hydration and volume help the meal feel balanced and satisfying without becoming too heavy.
