Help with lids

Hi all,
My friend , who lives on his own ,
Has just been diagnosed.
Although he’s had it for a while .
We know he doesn’t eat properly and we want to
Make sure he has a daily meal.
So we are going to make sure he has a meal every day.
Our problem is how to put the meals in microwaveable containers
That will be fairly easy for him to remove the lids .any suggestions?
