Packing lunches for kids

Homemade granola with whatever dried fruit they like, some chia seeds, oats and soy nuts.
Carrot stick with ranch for dipping. I try to sneak in hummus sometimes but they still haven't warmed up to that.
Any fruit - my kids will always eat kiwi.
Ants on a log - celery with peanut butter (or sunbutter in your case) with raisins
Homemade fruit muffins - I usually use half whole wheat flour and try to add something else like chia seeds in. I also use applesauce instead of butter, etc.

It's a little more work but you can make homemade baked goods that kids usually like but substitute some unhealthy ingredients for healthier options and try to add in some other nutritous stuff. Sometimes my concoctions are a complete failure but sometimes I get a good one to add to the recipe book.

Cheese sticks and applesauce, maybe some carrot sticks with ranch and clementine oranges!

I bought some thermos containers and often fill those with leftovers in the morning to mix things up and give them a change from sandwiches. I'll heat up left over pasta, rice and beans, chicken and veggies, whatever we had for dinner, and throw those in the kids lunches in place of sandwiches. I also give them little containers full of almonds, walnuts or cashews, and sometimes some raisens. (Again, I bought a bunch of stainless steel containers with rubber lids so I can fill those up with whatever I have handy in the pantry). I usually cut up some apples, oranges, carrots, celery or cucumber, or put in a whole mandarin orange (I skip the canned mandarins because they have a lot of sugar, same with Capri Sun - I just put water in a reusable bottle.) I sometimes put unsweetened apple sauce in their lunches. String cheese or cubed cheddar or jack is a good high-protein snack. For cracker replacement you could try Snap Pea Crisps, pretzels, rice cakes, or whole grain crackers. I avoid the processed snack-size pre-packed foods because they tend to be very high in sodium and have so many ingredients I can't identify. I try to stick to whole foods as much as possible. Oh, and I agree with muffins - those are a healthy, easy addition to the kids lunches.
