Combine yeast, sugar and water in a medium bowl.
Once it starts to bubble add the salt, oil and 3 ½ cups of flour.
Mix until there isn't any dry flour left using a danish whisk.
Dump the dough onto a floured surface and knead for 5 minutes.
If it seems too sticky add ¼ cup more flour.
Form into a ball and place back into the bowl.
Cover with plastic and let it rise for 1 hour or until it's doubled in size.
Dump the dough onto a floured surface and divide into 6 equal pieces.
Shape into oval shapes by gently flattening each piece and roll like a cinnamon roll, pinching the seam together.
Place seam side down on a parchment lined baking sheet and cover.
Let them rise until puffy, 30 minutes to 1 hour.
Heat the oven to 400 degrees.
Brush each bun with egg wash and score 3 slashes on an angle on the tops of each bun.
Bake for 15 minutes.
Cool and use for sandwiches.
