Proof the yeast: in a small bowl combine the yeast, warm water, and sugar. Stir to dissolve the yeast and let stand for 5 minutes, or until bubbles appear.
Whisk in the beaten eggs, milk, and salt.
In a large bowl, place the flour and make a well in the middle.
Pour the yeast mixture into the well and let it stand for 30 minutes without mixing.
Add the melted butter, and mix until a ball forms and you can knead the dough without it being sticky. Knead it on the counter for 5 minutes. You can add a bit more flour if needed.
Add about a teaspoon of oil to the bowl, and place the dough in it. Swirl it around until it is all covered in oil, cover it with a damp kitchen towel, and let rise for 30 minutes.
Remove the dough from the bowl, divide it into 15 equal parts, and shape them into balls by rolling them in a circular motion between the heel of your palm and the counter.
Place the rolls in a greased 9x13-inch baking dish, cover with a damp kitchen towel, and let rise for 30 minutes more. Brush the rolls with melted butter.
Preheat the oven to 400 F and bake them for 15 minutes or until golden brown.
