Sorry, no recipes, but I would strongly caution you against using agave as a sugar substitute, especially for children.

Fruit kebabs are always popular with my kids and their friends.

No recipes on hand, but when making banana bread, the riper the bananas, the less sugar you will need.

Breads are always welcomed by my crew. I sometimes roll out the dough, spread pizza sauce and then roll it into a loaf and bake. Yum.

You could do crudites with a choice of ranch dressing or Veganaisse.

And I know this sounds a little off the wall for kids, but I have had huge success with summer rolls.

Oh...and freshly popped popcorn either made in the air popper or my fave--in a pot with coconut oil! Add salt and nutritional yeast.

Chex mix with *vegan* worcstershire (sp) sauce.

Dried apples.

Pumpkin pie (just use almond or soy milk) is always yum. Sweeten with sucanat or date sugar.

Good luck!

EatingWell.com has a section with kid-friendly recipes rated by their readers. I've had good luck with some of their cookie recipes.

Straight up fresh fruit and veggies, of course, but you don't need to be told that. Especially if there are no nut allergies and you can peanut butter it up. White bean dip or other bean dips might make a good (and protein-licious) approximation of that delicious creamy-sauce-crunchy veggie situation.

At my mom's school the kids often get cups of mixed dried fruit and nuts--raisins, dried cherries, sometimes cranberries, almonds and walnuts, basically trail mix made up of excess produce bought by the USDA and sent to schools as part of the free and reduced lunch program. Potentially doable in terms of expenses if you are able to purchase in sufficient bulk.

Homemade fruit pops for the warm weather months, just fruit pureed and frozen in big ice cube trays or I think I recall something here on the kitchen about doing them in a loaf pan. Or frozen half bananas on popsicle sticks--you might not want to go the dip in chocolate route, but I've seen a similar thing done with soy yogurt and granola--dip, roll, and freeze.

These would be good if you omitted the topping and maybe found a way around some of the sugar? http://www.yourveganmom.com/your_vegan_mom/2008/04/ive-turned-a-co.html

Could you do like, kale chips and sweet potato chips from scratch? Might not want those little fingers helping you out with the slicing, but if you have a mandoline the sweet potatoes would go super fast.

Does everything need to be made ahead of time or are you making them each day? How much wiggle room do you have on how fresh the food can be?

I think I would skip baked goods generally or other sweets and focus on fruit, vegetables, and proteins. It sounds like you have some restrictions but they aren't the really hard ones. Smoothies with tofu, little PB&J, cut up fruit and vegetable, yogurt (dairy or soy) bar, etc. Save the baked goods for home.

(And I also don't think agave is a good sweetner for kids.)

I work as a cook at a preschool and I've had a lot of luck with the savory recipes from Baby Let's Eat! (http://www.amazon.com/Baby-Welcome-Books-Workman-Publishing/dp/089480300X), a cookbook geared towards feeding kids under the age of 5. They have a few baked recipes plus a bunch of snacky things, and everything has been gobbled up by my (very picky) charges. Good luck!

Also, DIPS. You would be shocked at how much more the kids will eat if it's an interactive snack. I make a mayo and sour cream ranch dip (not the healthiest, but they each only get a bit) and they'll eat as many cut up cucumbers as I can give them. Baby carrots are a big success, too.

Agreeing on the steering away from agave syrup use. It's not "low sugar", it's just another kind of sugar.

Really simple pasta or rice salads with fresh veggies are easy to make in quantity and ahead of time.

I'm not a fan of low-anything, so my German approach to eating less sugar would be to offer savoury sandwiches with good bread, cheese and/or vegan spread, maybe gherkins, olives (some kids like them) lettuce etc. or vegetables and grissini with dips. After eating something substantial, it's perfectly fine in my opinion have a little treat. A proper one, no low-sugar stuff.

My 4-year old would eat a mountain of raisins and pickles if you let him. And if he got to dip something? Oh boy.

I love making these pretzels from KAF - they're dairy-free and made w/whole wheat flour.

What about some raw bliss balls or similar? Whizz up some dates, cashews, almonds, seeds, raisins, peanut butter etc. to make a fudge-like substance that can be rolled into balls or made into a fudgy slice, set in the fridge. You can add cocoa powder and it makes excellent healthy fudge. Some recipes add a little butter or coconut butter, but I reckon enough peanut butter will help it to set. My daughter loves apple slices with peanut butter, you could also just do twists on ordinary things, like make your sandwiches pinwheels etc. Homemade trail mix is a great idea - you can add all sorts of things, like cheerios, veg crips, and yoghurt covered raisins to really bulk it up and keep it fun.
