Ingredient Substitutions: You can swap out ground beef for ground turkey, chicken, or even a plant-based substitute if you want a lighter or vegetarian option. Optional Variations: Add diced vegetables such as bell peppers, carrots, or spinach to the meat mixture for extra nutrition and color. For a spicy kick, consider adding a splash of sriracha or red pepper flakes. Storage or Reheating Tips: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop, adding a splash of water or soy sauce to keep the meat moist.
