Loco Moco is Hawaii's original homemade fast food and can be found at just about any fast food joint, roadside diner, mom and pop restaurant or lunch wagon in the Islands. There are many different versions of Loco Moco but they have 4 basic ingredients. Rice, a beef patty, sunny-side up egg and gravy. This is for 1 serving so you might want to share - it's a HUGE dish! The cooking time varies depending on if you have to make the rice or gravy from scratch. Enjoy!
