Yummy food for diabetic?

My mum is diabetic, and I try to get her to eat nore vegetables (I'm worried about her), but she mostly refuses to eat them, saying that she is "full". (And proceeds to get dessert the next second). She also sometimes argues that she has worked all day, so she deserves it - I understand that of course, but it worries me that this is not a once in a while thing, but pretty much everyday. She really, really dislikes vegetables (fruit is a bit better) and says she doesn't like the taste, etc. I think soups are somewhat ok, but thats about it.

So, I am posting here to ask if you guys have any tasty recipes that could help in that situation. Anythinh where the veggies are not that obvious, or overpowered by other tastes?

Would really appreciate it. Thank you.
