Toddlers and eating supper

I have an almost 2 year old and an almost 4 year old. I make supper every night and my 2 year old eats but not as good as she should. But my 4 year old will not eat what I make. Takes a couple bites and says she doesn’t like it. But wants snacks and juice. And I know this is common for kids their age. But my question is what did you do if they didn’t eat? Any suggestions? We don’t give her snacks at all if she doesn’t eat. But what can we do to get her to eat what we make?
