Place the flour and salt in a bowl. Add the beaten eggs and vinegar and mix thoroughly until a smooth dough has formed (use an electric mixer or food processor or knead the dough by hand). Let the dough rest, covered with plastic wrap, for 20-30 minutes.

Roll out the dough on a lightly floured surface until the dough is very thin, almost like paper (I usually roll it into a 14 to 15-inch circle). Cut into squares or rectangles or odd shapes. Heat about 2-inches vegetable oil in a deep saute pan (or use a deep fryer) over medium-high heat until the oil reaches about 375 degrees (a bread crumb or tiny piece of dough will sizzle quickly). Drop the cut-outs, a few at a time into the oil (they will puff up) on both sides until they are crispy and faintly browned. Drain on paper towels.
