Yeast-free bread "Eliopita" with onions and olives

Ingredients:

• 2 tbsp. l. olive oil
• 1 medium onion, finely chopped
• 4 cups sifted wheat flour
• 1 tbsp baking powder
• 1 teaspoon of salt
• 3/4 cup warm water
• 1/4 cup olive oil
• 1 tbsp finely chopped thyme
• 1 cup chopped pitted olives
• Milk for greasing

Preparation:

1. Heat 2 tablespoons of olive oil in a frying pan and add the onion. Lightly brown it, but do not let it caramelize completely. Let it cool.
   
   In a bowl, combine the dry ingredients: flour, baking powder, and salt. Add the sautéed onion to the dry ingredients. Then add the water, olive oil, thyme, and olives.
   
   Mix thoroughly until a dough forms. Transfer to a floured board and knead until a soft, smooth dough forms, about 5-8 minutes. Cover with a towel and let rest for about 20 minutes.
2. Preheat oven to 205°C.
   
   Form the dough into a large ball and place it in a greased loaf pan. Bake for 1 hour, until the bread is golden brown. When the bread is 10 minutes from done, lightly brush the surface with milk for a shiny finish. Remove the bread from the oven and cool on a wire rack.
