I try to let my live-with-me Mom be as independent as possible but she has impaired vision (large blind spots) and constantly puts very little food on her plate. For example, she stops filling her cereal bowl when it is only 1/4 full. Same with putting water in her glass - stops at about half full. Ditto any food that needs spooning from a container. I prepare her morning oatmeal and all dinners, but lunch can be an issue.
I've suggested many times that she feel the plate/bowl/glass or even count spoonfuls but she either forgets or just won't. I love things like bananas and peaches and foods that are already single serving.
Any tips for frugal food prep so she can get her own lunch?
