Start by mixing hot water with dry yeast in a bowl. In another bowl, mix the flour, baking powder and olive oil.
Pour the water with the yeast into the flour mixture. Mix and make a ball of dough with your hands. Cover with a towel and set aside for 30 minutes.
Uncover and knead for 5 minutes until your dough is soft.
Cut into 4 pieces. Using the rolling pin, open 4 round buns.
In a non-stick pan or wok, after pouring a little olive oil, bake the buns one by one. Bake each bun for 2 minutes on each side.
Open each bun in half (do not cut it to the end) and put in whatever you want.
To make the soy minced meat, heat 1 tbsp. olive oil in a pan. Add the chopped onion and garlic as soon as the oil heats up. Saute lightly and add the soy minced meat. Add the tomato sauce. Add salt, black pepper and ginger. Cook the minced soy and set aside.
Fill each bun with salad of your choice (I used coleslaw), minced soy, red pepper and spring onions and a little mayonnaise. Enjoy.
