The best stir fry I've come up with starts with Green Giant Stir Fry with Sauces.  It comes in three flavors and can be found in the frozen vegetable freezer.  I add my own chicken (boil chicken legs in lightly salted water until the meat can easily be pierced with a fork).   Or my own beef -  8 0z to 1lb top sirloin or strip steak cut into strips works well.  

Brown the beef or chicken in a large skillet, then remove meat from skillet and set aside.  Add one tablespoon of oil to the skillet.  Once oil is good and hot, add vegetables and keep flipping until hot.  Then add the meat back in and the included sauce, continuing to fold veggies over and over until stir fry veggies, sauce and meat are well heated through.

In the meantime, cook minute rice according to package on box, adding a couple pinches of sugar to the boiling water.  

When stir fry is finished, dish over rice for a delicious fast dinner!

I like to add a can of mushrooms to the stir fry, and, if I have them, a can of water chestnuts while frying.  When nearly finished I also like to add both green and black olives.
