TUnderstand the side-effects of other cooking methods, and choose to include them if you like.
Some cooking methods, such as frying, smoking, or boiling with salt or spices, also add material and thus flavor to the food. Microwaving doesn't add anything, so add all the flavoring (including "liquid smoke", smoke particles collected in a very efficient manner and dissolved in liquid) you like to the food before or after cooking. Add conservatively: only a very small fraction of the medium in which something would otherwise be cooked is actually absorbed into the food.
Some cooking methods add water to the food. Some, such as boiling (with water to be discarded) add way too much, so that it leaches out vitamins. Generally all that is needed with items prone to drying out is some plastic wrap with a few holes to prevent pressure buildup, but if something is on the edge of over drying, add just a little water and cover it.
Some cooking methods dry out the outside of the food. Microwaving will liberate steam and re-moisten it, so if a crispy outside is desirable, generally microwave to get the inside mostly done, then cook the outside.
