"My kids are preschool age, so I know they are not going to eat certain things."
This looks like an excellent example of an excuse framed as a fact. I am so guilty of this and am trying to spot them and reframe them. Challenge it. Who says the kids won't eat healthier foods? Kids all over the world eat foods that are very different from what we eat. Put a positive spin on it - the more Mom likes it and seems to "buy-in" to it yumminess, the more the kids will. Actually, this is the BEST time to teach them to eat better. As they get older, it gets harder.
Best wishes to your friend as she discovers how much better food tastes when it's actually food and to you for being such a great friend to her!
