In a large bowl, dissolve yeast in water.

Add sugar, egg, salt, and 1 cup of flour; beat on low speed with an electric mixer for about 3 minutes. With a wooden spoon, add enough remaining flour to form a soft dough. Turn onto a floured surface and knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl and turn once to coat the top. Cover and let rise in a warm place until doubled, about 1 hour.

Meanwhile, in a skillet, brown and crumble beef with the onion over medium-high heat until the beef is no longer pink. Drain. Add bacon and cheese. Add BBQ Sauce to taste. (We like ours the consistency of a less-sloppy Sloppy Joe). Mix well. Remove from the heat and set aside to cool.

Punch down dough and divide into 8 pieces. Roll each piece into a 6 in. circle. Top each circle with about one-eighth of the filling. Fold dough over to meet in the center and pinch edges to seal.

Place seam-side down on a greased baking sheet. Cover and let rise in a warm place until doubled, about 30 minutes. Brush with butter. Bake at 350°F for 20 minutes or until golden brown.

Serve warm.
