Our Test Kitchen couldn't get enough of these new sloppy joes enlivened with a splash of cola, which gives the ground beef a sweet boost that plays well off the filling's spices. Try these with traditional or split-top hot dog buns or hoagie rolls. Garnish with your favorite coleslaw for crunch and color.
The key to this dish is developing a nice char on the green beans. To do so, heat the oil in your skillet until it almost smokes before adding the beans. Let them sear, stirring every 20 to 30 seconds, and they'll take on color. Feel free to sub thinly sliced strips of red bell pepper instead of hot chiles.
