Your children could even share an order of fries. Another good choice is a grilled chicken sandwich. You'll add more vitamins if you order with lettuce and tomato, but skip the mayonnaise and special sauces. Many children would rather have a chicken piece, that's fine. Just order a smaller serving size to keep the fat content down.
Tacos can also be a good source of nutrition for kids.
Chicken soft tacos are lower in fat than the beef tacos. The beef tacos however can be a good source of iron for your youngster. Skip the sour cream though. The bean burrito is better choice over larger burritos especially ones that contain sour cream and sauces. When it comes to nachos, smaller is better.
