Mix water, oil, sugar, and yeast. Let sit 15 minutes for yeast to proof. Pour into large bowl or electric mixer. Add salt and eggs. Mix well. Add flour gradually, then mix with dough hook or knead by hand until dough is elastic.
Place dough onto floured surface. Divide into four equal parts. Roll first part into circle, about 1/4 inch thick. Spread with melted butter.

Let rest/raise 10-15 minutes.
Bake at 350 for 12-15 minutes until light golden brown. Remove from oven and brush with melted butter.
