This is a copycat version of the Japanese Samurai Big Mac Burger that you can only buy at McDonald’s in Japan. The keto beef burger patty is grilled and then dunked in a thick sugar free teriyaki sauce and topped with lettuce pieces and caramelized onions, with special lemon mayonnaise coating the inside of a moist sesame seed-topped gluten free keto hamburger bun. This keto Samurai burger is so tasty that you do not need more than the basic toppings, but you can dress it up to your taste for a complete, healthy, budget friendly meal, as I did.
