I have two little ones... and the only way I can survive is with my crockpot and my bread machine. I throw the ingredients in the cp in the am... throw other ingredients in the bread machine and I have homemade bread and soup/whatever for dinner. (Other than they take longer to bake/cook, but that's hands free/brain free cooking). It's as healthy as I want to make it... i.e. some nights it's a super healthy veggie soup, other nights it's an open can/dump dinner that is less healthy, but healthier than eating fastfood.
I also cook steel cut oats in the cp overnight for oatmeal for breakfast a few nights a week.
