I raised two sons and it was always difficult to get them to eat greens of any kind. I tend to portion and freeze spinach into tbsp portions, finely chopped and throw them into soups I make like chicken vegetable or chicken noodle.

The grocery list shows where much of the fault is.....buying all of the foods that contribute to the obesity. My sons love pancakes so I put fresh berries into them or bananas. Tacos are a good option, provided the toppings put on it are portioned properly with more vegetables in them than dairy products like sour cream and cheese. Dairy products are also available in less fat but watch for sodium and sugar levels. Yogurt is a popular option and Greek Yogurt specifically, also contains protein. Omelets are a good way to put veggies into the meals. Pizza is a great option if they put veggies into the meat and cheese. The national food guide is a good start.
