Commentary for Pesachim 199:6
דתניא מפסיקין לשבתות דברי רבי יהודה רבי יוסי אומר אין מפסיקין
this is R'Judah's ruling. R'Jose said: One need not interrupt [the meal].<span class="x" onmousemove="('comment',' But he completes the meal, recites grace, and then kiddush. Now when R. Jeremiah states that the halachah is as R. Judah in respect to Passover eve, whence it follows that R. Jose disagrees there too, this disagreement is likewise in reference to interrupting the meal, R. Jose maintaining that even on the eve of Passover he need not interrupt it once he has commenced (i.e.,if he commenced at the permitted time - Rashbam and Tosaf) . But he admits that a man must not commence a meal in the first place shortly before minhah, and that is the meaning of the Mishnah too.');"><sup>6</sup></span>
