Ingredients:
-rice
-Bell Peppers
-minced onion
-eringi mushrooms
-ground beef
-diced tomatoes
-minced garlic
-fresh basil (if you have it!)
-spinach
-cheese
Cook the rice, it can be the day before or in the morning. (Yay! Something for used rice other than chahan! [fried rice]) I used white rice with a small packet of beans and sesame and black rice. I'd be interested in trying with brown rice. You only need a cup or two.
Stir fry the onions and the eringi mushroom (trying a different mushroom would be fine, but I like the meatiness of eringi), and once the onions are turning clear add the ground beef and the garlic. After the meat has browned, add the tomatoes (I used boxed canned tomatoes with sauce) and the basil, and cook down. Turn off the heat and let cool a bit.
Cut out the tops of the bell peppers, and put in a table spoon of rice at the bottom to catch the juices. Then mix the rest of the rice to the sauce, and add as much cheese as you like (a lot if you're me!), mix well, and then stuff the peppers. When it was nearly full, I stuffed some cheese in and then covered it with another spoonful of stuffing.
Put in a baking tray with an 1/8th of an inch of water at the bottom, and bake at 170C for 30 minutes.
