Working mom of 3... Meal prep HELP!!!!

I'm a mom of 3 boys and I was prepping for a bit there but have been slacking lately. I would make a cookie sheet of broiled chicken breast on a rack in the sheet and a cookie sheet of veggies. It would make about 8 lunches for or work. I would also make a couple dishes of spaghetti or a big portion of whatever my kids liked that I could have them eat for 3 days each. Or 1 big hot meal and sandwiches or salads. I would also look on Pinterest or the web for recipes and ideas. Good luck.
