I've been asked to bring an appetizer to Thanksgiving dinner and my father requested that I make him my beef wellington so I'm wanting to try a bite-sized version. It's a family potlock and there won't be time to cook a dish but we'll keep the oven at 350F and use it to warm dishes as needed.
Although my mini wellingtons will be fairly small (about 1.5" cubes) I'm concerned that the `10 minutes it will take to bring them to a proper temperature will overtoughen the meat inside.
Do I have any reasonable options or should I consider a different dish?
