You have the consider the fact that there is the sandwich itself and the dip that comes along with it. Stew heals 500 lp, and a sandwich heals anywhere between 60-340 lp. Assuming that the quality of the Arby's French Dip is medium-medium high based on LTK's taste bud readings, I will safely put the sandwich at 300 lp. Since the drip not actually a stew (not to mention a smaller portion than a stew), we will assume that it heals for 100 lp at most. Therefore, our grand total for the meal, assuming no fries, drinks, or turnovers, would be 400 lp. This is nowhere near a monkfish or a rocktail soup.
