I'm trying to involve my 5-year old and 3-year old more in meal planning and eventually cooking. Right now, they're a bit picky (like most) and so we have a pretty limited set of maybe 5-6 dinner options.
My goal is to broaden their choices. For example, I found that when we started making pizza, my daughter, who doesn't like tomato sauce on pasta, suddenly thought it was OK.
What are good approaches to make young kids become more involved in meal planning and cooking? What is your personal experience with this?
For example, I thought that a cookbook with lots of photos and generally kid-friendly foods, that are easy for kids to help with many steps, could make them look at some photos of meals and say "oh, that looks interesting".
