In a small bowl, mix the yeast, 1 tspn sugar, and 1 tbsp flour. Add 1/3 cup warm water and stir well. Cover the bowl with plastic wrap or foil and allow yeast to ferment in a warm place for about 20 minutes.
In a large mixing bowl, add the eggs, 1/2 cup sugar, melted butter, and 1/2 cup warm water. Mix thoroughly.
Add flour, salt, and yeast mixture to the large mixing bowl. Mix until all of the ingredients have combined. Add a little more flour, if necessary, so that dough cleans the sides of the bowl.
Turn dough out of bowl onto a floured surface and knead until dough is soft and smooth.
Form a round loaf and place in a bowl. Cover with a dry towel and let dough rest in a warm place for about an hour.
Preheat oven to 350 degrees Fahrenheit.
Divide dough into three parts and roll out each part to form a large rectangle. From each rectangle, cut triangles (about 10cm by 12 cm).
