This can be gluten free using quinoa or rice, and rice flour.
This recipe is easy, it makes 6 meals and calls for:
Boil the noodles or rice in a big pot with 3 parts water for 1 part rice. Don't overcook this, it will be cooked a little more after.
Cook the beef in a pot and remove. Cook the onions in that pot, Then add oil/butter and use it to cook the other vegetables a little, mushrooms last. Then add some miso paste and put the beef back.
When the rice is done, add the beef/veggies in the big pot.
Add the sour cream last, when you turn the stove off and you are ready to serve.
