Packed lunches for the whole week and my kids actually ate them

I know this sounds simple but I usually just throw random stuff together and half of it comes home uneaten. Last Sunday I meal prepped like I was running a restaurant. Did the sandwiches, cut up fruit, packed chips in little containers. This week every lunch came back basically empty. My 8 year old told me my pasta salad was better than his friends lunches. I'm never going back.
