the.com/silver platter

means Something given to you fully prepared, requiring no effort, skill, or struggle on your part — usually said with a faint sneer about how you got it.

from Drawn from the literal image of food or gifts presented to the wealthy on silver trays, by servants, with zero exertion from the recipient. The phrase 'born with a silver spoon in one's mouth' is the older cousin of this idea (traced back to the 1700s, referring to infants of rich families fed with silver rather than wood or horn), and 'silver platter' grew out of that same vein of imagery — the thing you receive while someone else does the carrying, the cooking, and the serving.
