This is the dish you need to try if you're looking for a way to transform ground beef into something so simple yet mind-blowing. All you have to do is brown the meat in a wok with some sauces (soy, sweet chili) and spices (garlic, parsley, sesame seeds), neatly tuck the stuffing into romaine lettuce cups, and munch away! It's a great low-carb option and proves that few ingredients can go a long way.
