Pour the warm water, yeast and sugar into a mixing bowl. Let it sit for a few minutes or until the yeast bubbles. Then add the oil and a couple cups of flour, mix together until incorporated. Then add the salt, remaining flour, italian seasoning, garlic powder and seasoning salt. Mix the dough together for 5 minutes and then let it rest for 10-15 minutes in the mixing bowl. Separate the dough into two equal portions on a greased counter. Roll each dough ball into a rectangle and with a pizza cutter cut the dough into evenly sized strips. Take each dough strip and form into a round, twisty breadstick by doubling the dough onto itself and twisting. Place the twisted breadsticks onto a greased cookie sheet. This recipe makes enough breadsticks to fill two cookies sheets. Brush the breadsticks with melted butter and sprinkle with more garlic powder and seasoning salt. Let the breadsticks rise for 10-15 minutes, or until the dough has doubled in size. Bake at 350 for 12-15 minutes, or until they are lightly golden brown.
