Kid Lunches

I am a SAHM and do in-home daycare for several additional kids each day. As my husband and I have changed our lifestyles and been losing weight this year, our kids are adapting very well along with us. DH and I have lost nearly 75lbs between us to date One of my biggest NSVs is offering my kids, and my daycare kids, healthier options. I find it's not hard to offer them reasonably healthy breakfasts. We do a lot of cold cereal, oatmeal, yogurt and fruit. I'm satisfied with this.

But lunches are harder for me. The kids like your typical pre-school stuff: PB&J, hot dogs, mac n cheese, chicken nuggets etc. As a result, this is pretty common for their lunches, with the big difference being what I feed them on the side. Now instead of nuggets & fries, they may get nuggets, apple slices and string cheese. I don't often provide veggies for the kids, because they're all so particular about which veggies they will/won't eat, and I feel like that's a battle for their parents to fight. But I like to provide them with a fruit and often some cheese or yogurt on the side.

What I'm wondering is, what are some less-processed options you find that your kids like? The kids I feed range in age from 22 months to 6 years old. Easy is better (hence the nugget/hotdog/sandwich variety my kids often get). Like I said, I'd just really like to provide them with some less-processed, slightly healthier options, even if only a couple times a week. I have no problem with the kids eating a hot dog on occasion, but I'm in need of some healthy variety. Thanks!
