- To make the buns, in a medium bowl combine water, milk, yeast and sugar. Stir and let sit 5-10 minutes, until mixture gets foamy.
- In a large bowl, combine flour and salt. Slowly stir in melted butter and yeast mixture. Using a mixer or your hands knead the dough until smooth. Cover with a towel or plastic wrap and let rest until doubled in size, about 1 hour.
- Meanwhile, make the mushrooms. Add olive oil to a medium saucepan set over medium heat. Add garlic and butter and cook for about 1 minute, until fragrant. Add the sliced mushrooms, salt and pepper to taste. Cook for another minute, then stir in vegetable broth. Simmer for 1-2 minutes, until the vegetable broth has cooked off. Remove from the heat and transfer to a bowl.
- When the brioche dough has doubled in size, dust a work surface with flour. Scoop out dough onto surface and knead until smooth. Divide into 4 portions. Roll each piece into a smooth, round ball and place on a sheet pan. Repeat with remaining dough and let balls rest for 30 minutes.
- Preheat oven to 390°F. Brush buns with the maple syrup and sprinkle on with some sesame seeds (optional). Bake for 13-15 minutes or until the buns are lightly golden brown. Cool completely before slicing.
- Cook plant-based fish burgers according to package directions, until lightly crispy.
- To assemble burgers, slice buns in half. To each bun bottom, layer lettuce, burger, hot sauce, mushrooms, cucumber, tomato, onion and microgreens. Add top and serve.
