I've suggested to my husband that he cook or order in food, but he says they need a wholesome, home-cooked meal.

Anyone want to bet that husband would not consider "dish in a crockpot" or "dish easily reheatable" to be a wholesome, home-cooked meal?

If his response to "how about you cook then, or we can order takeout" be "my kids need a wholesome, home-cooked meal" he's living with sufficient pre-conceived notions of what that means that I bet he wouldn't consider any shortcuts such as the crockpot acceptable.
