Idk what your living situation looks like but if it’s possible for them to have the microwave in their room or something that might be the best option. If you’re in a dorm there are sometimes communal spaces that have microwaves they could use. Idk if they would be very receptive to nyxing their go to meal, but if you’re friends and not randomly assigned you might have more luck with asking for a change
Idk how strong it is, but keeping a window open/cracked in the kitchen could also help. I think it’s absolutely worth taking care of the situation in one way or another and if other solutions don’t work the best option is they stop eating that food. Maybe snag them a different freezer meal the next time you go to the store and say “i saw this and thought you’d like it.” If they like it enough they might switch without you even needing to bring it up
