I don't have kids, but both parts of the meal I made last night would be pretty favourable for kids, I think. If you have trouble getting your little ones to put away chicken and potatoes, this is an easy way to turn some boring standards into slightly more kid-friendly foods!
First, breaded chicken cutlets. Here's the recipe from Bon Appetit - Parmesan Chicken Cutlets.
These aren't hard to make; the annoying part really is making the cutlets because Canadian grocery stores don't seem to sell chicken cut in quite this way. I bought four of the smallest boneless skinless breasts I could find, and sliced them in two. So, 8 total, about 1.5lbs total, and with that much chicken I found I only needed half of the flour and breading mix that the recipe suggested. Cooking-wise, they really do only need 4 minutes per side MAX - be careful not to burn them. Then the oil gets all burn-y and your house will get all smokey and yuck.
The other side of the plate are slightly spicy, smokey potato "fries." Tossed in olive oil, some spices, and baked rather than fried. Here's the recipe, same issue of Bon Appetit - Spicy Oven Roasted Potatoes.
The trick here that I got wrong is they're looking for russet potatoes which are harder to find around here and generally are smaller than our large baking potatoes. Baking potatoes will do fine for you, but you'll want to cut them into more than 8ths. Try and get 10ths if you can. The thinner they are, the crispier and more French fry-like they'll get.
Then bam, you're done! Kid friendly chicken & potatoes. Oh... you want them to like vegetables too? I'll leave that one up to you.
