cut the round steak thinly into strips. You can alternatively use chuck roast.
Brown the meat in a skillet, sprinkle it with the garlic powder while browning.
When steak strips are browned, add 1 cup of water (or the liquid from the can of bean sprouts), the soy sauce, and the beef bouillon cube. Transfer this to a crock pot and cook them on high for a couple of hours.
While the strips are cooking and tenderizing, Roughly chop the peppers into pieces about an inch square. You should end up with around four cups of peppers. Also chop the onions into large pieces about an inch square, and cut the carrot into matchstick pieces about an inch long. (the carrot is really mostly for color).
After the meat has cooked for two hours, it will be quite tender. Add the peppers and onions and carrot and cook until they are as done as you like them. It will take between 1-2 hours depending on how crispy you like them.
When they have reached the desired crispness or doneness, add the bean sprouts and stir them inches.
Serve with chow mein noodles sprinkled on top, or over rice. The sauce really doesn't need thickening, but if you wish to thicken it, stir in 1/2 cup of cold water mixed with a tablespoon of cornstarch to thicken it.
