I have 3 grown children. My 2 boys are still poor eaters. My girl was a healthy eater from the beginning. I thought I tried everything, but had little to no success. 

My youngest boy is special needs so getting across to him WHY he needs to eat healthy is challenging. HOWEVER, I have given up sort of on explaining why and cajoling and cook everything for him out of ground turkey and ground up/pulverized vegetables. I make turkey burgers, turkey tacos, turkey meat loaf, turkey burritos, turkey pizza, turkey chili....well you get the picture. Each of these items is lean ground turkey mixed with ground up broccoli, onions, tomatoes, squash, bell pepper, green beans, spinach...you just about name the vegetable and he gets it in his food. I've been doing this a year and his behavior is MASSIVELY better. He's lost 20 pounds, also. 

Since he's special needs the key to this is I freeze the food in serving-size portions. And I keep the freezer full. When he's hungry he can't wait to eat, so it's right there, ready to be heated. It has worked for us. I wish he would eat the real vegetables but honestly, at 63 years of age, I'm tired of fighting that battle. This is easier than fighting and it's working!
