Re: long hours
Yipee it works !
Try Sat planning the weeks menus. Planning with your family is even better.
Use a crockpot with cheap cuts of meat and make two meals...one night with veggies next night use flour tortilla for wraps.
Try Pillsbury pizza dough and top with veggies and meat,,they have reg and thin crust.
Make breakfast for dinner,,use leftovers with scrambled eggs, easy and quick .
Check this site for easy recipes, lots are listed. Good luck !
