So, we don't want to leave a crockpot on and running while we're gone. But we do use the crock pot when we're home all day.
I get it if you are uncomfortable with letting it operate unsupervised but the crockpot cooking while we were at work was a lifesaver for us for years. dh and would meal plan stuff and prep veggies/soak beans/premeasure ingredients to toss in right before we left for work. when we got a bread maker we were set b/c we we set it up so we walked into the house to the smell of fresh hot bread and stew/soup/beans....ready to serve up.
I know you attend your church-do they ever do classes for members? I remember attending a 'quick-n-easy' cooking class at mil's church when dh and I were first married. someone got volunteers to offer up their go-to recipies for busy times (with bonus points for being budget friendly). they gave some simple instructions, provided each participant with a little print out of the recipies and we all had a potluck of the featured items. if your church does'nt do something like this you might suggest it (it was fun and informative).
