For dough:

• Preheat oven to 350°F and line 2 rimmed baking sheets with parchment paper.
• Mix oil, eggs, sugar, vanilla and salt together, using a hand mixer, or by hand in large bowl until combined.
• Slowly add 1 cup of flour at a time, mixing well after each addition until a smooth dough forms, about 15 minutes.
• Turn dough out onto a lightly floured surface and knead until dough is no longer sticky, about 2 to 3 minutes.
• Cover with plastic wrap or an inverted bowl and allow to rest until dough is supple, about 30 minutes.

For coating:

• Sprinkle 1 1⁄2 cups sugar evenly over work surface and roll dough out into a 1⁄4-inch-thick rectangle.
• Top evenly with remaining sugar.

• Cut dough into 1- x 2-inch rectangles using a sharp knife or pizza cutter.
• Twist each strip to form a bow tie shape. Place onto prepared baking sheets, 1-inch apart.
• Bake cookies, 1 rimmed baking sheet at a time, until edges are lightly browned, about 20 to 25 minutes.
• Transfer cookies to wire rack and let cool completely before serving.
• Store cookies in an airtight container at room temperature until ready to serve.
