Oh my....your kids have more choices than mine...lol...but, I find know that mine are older, I don't come up with "inspiring" lunches, they make what they want which includes:
Lean Cuisines
Healthy Choice meals
Pizza rolls
Ramen noodles
Grilled cheese (with ham or turkey)
Tortilla roll-ups
sometimes canned pasta
sometimes eggs & toast
sometimes canned soup
PB&J
appleasauce, yogurt,fruit
It was so much eaiser to get them to eat healthy when they were little and really didn't have much control over what they ate.
