Would it be acceptable to split a third meal on Shabbat into the third meal and melaveh malka? So instead of having 2 pieces of bread and sides, have 1 with half the side and the same after Shabbat ends? I ask because Shabbat ends earlier in the winter, and I prefer to eat later.
Thank you for your question.
Yes you can split the third meal, bentch after eating only one roll, and eat the other one instead for Melava.
