Tosca Reno has THE best cookbook for healthy recipes for kids. My kids LOVE the chicken nuggets from the cookbook.
We also made (easy) pork tenderloins 2 nights ago, which they'd never had, but RAVED to everyone how great they were:
1/2 cup olive oil and 2 cups of Ian's Italian breadcrumbs and mix together. Take the pork medallions and press them on the breadcrumb mixture and cover the entire medallion. Put them in a baking dish, cover with foil and put in the oven for 35 minutes on 425F. We paired the pork with green beans, broccoli, cauliflower, peas and onions....with sea salt, of course!
