This is a dish from Okinawa and has become very popular throughout all of Japan(if only they knew it was really a Mexican dish in disguise). It works really well if you don't have tortillas handy and/or you have a ton of rice.
1 lbs. ground beef
1 package taco seasoning
2 cups-ish grated cheese
1 head of lettuce
3-4 cups short grain rice
1. Start you rice cooking. Follow directions for your rice cooker or in a pot on the stove follow a 2-1 ratio(2 cups water for every 1 cup rice) and boil. You migh want to make more than you think you'll need, it disappears fast, and if you have left overs you can wrap a serving in saran wrap and freeze for later use (just pop in the microwave for 2-3 minutes).
2. cook ground beef, drain, add taco seasoning and water as directed by the package.
3. dice the tomatoes
4. shred the lettuce
5. dice the avocado
dish out the rice, put the beef on top along with tomatoes, lettuce, avocado, salsa, cheese, oh and sour cream tastes good too. Anything you like on your tacos works. Great for kids with wheat allergies!
