If you're looking for a nice, brown crispiness to the outside of your food, don't put too much in your pan at once. When cooking meat or tofu, adding too much to the pan at once causes the temperature of the pan to drop quickly, resulting in the food sticking to the pan. In the case of vegetables, if you add a pile of them to a hot pan, they are more likely to steam and become soggy as opposed to browned. So consider cooking in batches to avoid sticking and steaming.
