Let's roll. Preheat the oven to 375°.

First, for the filling, combine first 11 ingredients in a large bowl. No art to it, just throw 'em all in there and mix 'em up.

Coat a large nonstick skillet with cooking spray and heat over medium-high. Add the ground beef mixture to pan and cook for 8 minutes or until done, all while stirring occasionally. Stir in the cabbage and cook 4 minutes or until cabbage is tender. Remove the skillet from the heat and let it cool completely.

Next, the dough. Lightly spoon flour into dry measuring cups and level off the top with a knife. Combine flour, baking powder, and salt in a large bowl and stir with a whisk. Combine 1 1/3 cups water, honey, and canola oil, again stirring with a whisk. Add water mixture to flour mixture and stir until a soft dough forms. Turn dough out onto a lightly floured surface. Knead the dough for about 5 minutes until it becomes smooth and elastic. Cover it up and let stand 5 minutes.

Roll the dough into a 16 x 12–inch rectangle (about 1/4-inch-thick) on a lightly floured surface and cut it into 12 (4-inch) squares. Working with 1 square at a time (put a towel over the remaining dough so it doesn't dry out), spoon about 1/4 cup of the beef mixture into the center of each square. Moisten the dough's edges with water and bring 2 opposite corners to center, pinching off the points to seal. Do this again with the other two points and pinch all 4 together to make one sealed point. Place rolls, seam side down, on a baking sheet lined with parchment paper. Combine 1 tablespoon water and egg white in a small bowl, stirring with a whisk. Lightly brush tops of dough with egg white mixture, then sprinkle each with 1/4 teaspoon sesame seeds. Finally, bake the sheet at 375° for 25 minutes or until rolls are lightly browned. Remove the rolls from the baking sheet and let them cool on wire racks.
