How far ahead can I prep and/or roast a stuffed breast of veal?

For Passover I want to prepare a breast of veal (unboned) stuffed with matzoh farfel stuffing (same ingredients as bread stuffing - celery, onions, egg, stock, but with matzoh pieces instead of bread). You prepare and cool the stuffing, stuff the veal, and roast low and slow. I will put some liquid on the bottom of the pan. Ideally I'd like to do everything at least a day ahead and reheat. None of the recipes I found talk about this. I found a recipe for braised stuffed veal that says can be done ahead, but my preparation will have less liquid. Julia Child's recipe says prep can be done ahead, but not the cooking. Can anyone help? Thanks in advance!
