In conventional cooking, slow to moderate heat develops tenderness and full beef flavor. In microwave cooking, however, the rapid rate of heating food tends to produce less than tender results. One solution to this problem is to select a lower power setting when using a microwave oven so the food cooks at a slower pace.
Another suggestion is to marinate the beef in either vinegar or lemon juice which also adds additional flavor. You can also make less tender beef cuts more to your liking by pounding them or cutting them into thin strips before cooking.
