In a large bowl, mix the water, oil, sugar, and yeast. Let sit until it blooms, about 10-15 minutes. Add the beaten eggs, salt, and flour. Stir together.
If doing by hand, turn the dough out onto lightly floured surface and knead until smooth- about 5 minutes. Adding more flour if needed until the dough does not stick to the surface. May use a heavy duty mixer if desired. When the dough comes away from the sides of the bowl you have enough flour. Knead for 5 minutes.
Preheat the oven to 425. Roll the dough out 1/2 inch thick on a lightly floured surface. Shape the dought into different size buns as desired.
Spray baking sheets with cooking spray and place the buns about 2 inches apart. Cover with a dishtowl and let dough rise for 15 minutes. Bake 5 minutes on the bottom rack, then 5 minutes on the middle rack. Let cool on a wire rack. Store in plastic bags until ready to use or freeze for up to 3 months.
