Must one who provides cooked food for an expiatory oath feed the needy both lunch and dinner, or is it permissible to suffice with a single, fulfilling or unfulfilling, meal?

The expiation for an oath is to feed ten poor persons from the average food one feeds their own family, or to clothe them, or to free a slave. Whoever cannot find [the means to do so] should fast for three days. The amount of food for feeding is a mudd of rice or its equivalent (approximately 750 grams), and it is best that it be from the average of what the one performing the expiation and their family eat. It is sufficient to offer them one satisfying meal, and it is not a condition to transfer ownership of the food; rather, it is permissible to feed them in the form of a banquet or an invitation, and this is the most preponderant opinion.
