I actually like this idea! I remember when the LX ZRH A/B lounges were closed for renovation, and we had the option to get a sandwich or fruit, plus a drink from a few of the eateries in the airport. I appreciated being able to take something to eat on the plane, where on flights like ZRH-MXP the only catering was chocolate. I found it convenient and practical, and might have preferred it to going into the lounge to eat.
