Has the dairy lobby taken over? Cheese is not that healthy, but OK every once in a while.
For sandwiches go with turkey, chicken breast or tuna on whole wheat or thinly sliced rye. Add lettuce, tomato and a light smear of mustard, horseradish or salad dressing depending on what your kids will eat.
Adjust portion size based on the kids’ physical activity.
Yes on the veggies. Baby carrots and celery sticks are easy.
For fun add a handful or two of honey nut cheerios (still pareve the last time I looked)
