I love the idea of getting your kids involved in making dinners. I don't have kids myself, but I can remember that growing up, my favorite meals were the ones my mom would ask me to help with. Specifically, I can remember making spaghetti and, of course my favorite, pizza.
If you ask for your kids' help with making a meal (whether it's breakfast, lunch, or dinner) they will be much more likely to eat it. This is a great way to get picky eaters to enjoy a meal with you and to hopefully sneak in some veggies.
Some ideas for things kids can help with include pizza, taco bars, loaded baked potatoes, salads, or a pasta dish where they can add the vegetables they like. Have everything cut up for them ahead of time and let them decide what they want to do. The ideas are endless - get creative!
