In a bowl, combine the dry ingredients (flour and salt), and mix thoroughly.
In another stainless steel bowl, combine the water and yeast, using spatula, then the oil, mix well. Let rest for 5 minutes.
Pour the water into the center of the flour, and with a spatula, stir to combine well into a sticky mass.
Pour this mass out onto a lightly floured surface and begin to knead the dough until dough is free of stickiness.
Brush another stainless steel bawl with oil. Place the ball of dough in it. Cover with a clean cloth and let rise at room temperature until it has doubled in size.
When it has risen in the size, punch down the dough, and divided into two balls. Roll each ball onto the floured surface, then top it with any kinds of topping you like.
