Proper microwaving is what gave rise to the entire concept of "fast casual" restaurants, famously AppleBees (or "club B's" in the late night focus iterations!)
Complex entrees that could be partially cooked and frozen. Then rapidly microwaved on a custom program that varies the timing and intensity of cooking. Then finished on a grill or conventional heat source for less than 1 minutes.
Microwaving food generally produces a lower quality finished product. But you can take a similar approach at home. The short cut is to just double the cooking time and cook at 50% power. Then throw whatever the item is in a preheated pan for about 1 minute if it's applicable. Other variations are possible too, I air fry finish most things like chicken nuggets, tater tots etc and the difference is considerable while still offer a significantly reduced cooking time.
