Instructions

• Split the 6 kaiser rolls and toast them until lightly browned; set aside.
• Preheat a medium skillet over medium heat. Add the 1 pound ground beef, the 1 small chopped red onion, and the 2 minced garlic cloves. Cook, breaking the beef into pieces, until the beef is no longer pink and the onion is tender (about 6–8 minutes). If there is excess fat in the skillet, carefully drain it.
• Stir in the 1 (15-ounce) can tomato sauce and the 1 teaspoon dried oregano. Bring the mixture to a boil, then reduce the heat and simmer 8–10 minutes, stirring occasionally, until the sauce thickens.
• Divide the 2 cups chopped Romaine lettuce evenly among the bottom halves of the toasted kaiser rolls. Spoon the sloppy joe mixture evenly over the lettuce.
• Sprinkle the ½ cup crumbled feta cheese evenly over the sloppy joes, close the rolls, and serve.
