Use lean ground beef (90% lean or higher) to reduce excess grease. For extra flavor, add a splash of apple cider vinegar or smoked paprika. Simmer uncovered for a thicker sauce if desired. Toast buns lightly before serving to prevent sogginess. Variations include adding chili powder for spice, substituting ground beef with lentils for a vegetarian option, adding extra veggies like mushrooms or carrots, topping with cheese, or swapping brown sugar for honey or maple syrup.
