Some other suggestions. Have fun with the food. Try different compositions and angles. Let the food speak to you. Have fun with lighting. Try to avoid harsh shadows or too much frontal lighting as it will flatten the appearance of the food in the pic. Turn off the camera's onboard flash if that's an option.
For instance, these deviled eggs are kind of a fun food, so I took the pic from overhead instead of at a more traditional angle.
Or maybe you want to show the texture of something like in this loaf of bread I made. Used lighting from an open window to light up the loaf.
Or perhaps just a tighter crop to make the plate appear full of food.
