This is really easy to make if you have an electric frying pan
Cubed steak
Need: cubed steaks, diced tomatoes (if you go canned I recommend gettting one that has some jalapenos in it as well), onions, green peppers
Cut up peppers and onions, I usually use 2 each. Brown steaks in pan with a little oil or water, usually takes about 8 minutes on each side. After the first side is done, toss in the peppers and onions and add a little water so they don't stick. Keep the frying pan covered to generate some steam. When you've cooked the steak on both sides add in the tomatoes and turn down heat. Leave it covered for a few more minutes and mix it all up. Serve over rice.
There's usually a bunch of pepper/onion/tomato left so I throw it in some tupperware for lunches. Just season up a chicken breast and broil it in the oven until its done, then add the leftovers and throw it over rice again
