I have realized that there are days of the week that I will be more exhausted (mondays I do laundry all day AND clean the rest of the house deep cleaning wise) so I won't want to make some elaborate meal. Those days I often toss something in the crockpot (have you seen the cookbook called, "Not your mother's slow cooker cookbook"?) or plan for my standby sweet potato/black bean quesadillas. There are many great cookbooks you can borrow from the library that have meals which can be made quickly with a minimum of effort. I have a variety of that kind of book on my shelf, from Rachel Ray (meh...not my favorite, but some good stuff) to One Pot Meals, to Cook's Illustrated 30 Minute Meals, to Meals in Half the Time... even if I don't cook every meal from them, it means that I have some decent ideas of what to make.
I say all that because when "I" waffle from the meal plan, it's typically cause I'm tired, don't have help, and don't FEEL LIKE COOKING.
We had a million and half diet restrictions, which pretty much also meant that we couldnt go out and eat, but made it such a pain in the rear to cook that I wanted to cry some nights.
I agree that perhaps you should make your big meal for when you have an extra set of hands in the house. That always makes cooking easier!
The meal plan isn't supposed to stress you out, it's supposed to make life easier. SOoooo, don't waffle. If hubby says, "What's for dinner?" Say, "What's the date? It's on the calender on the fridge. That's what's for dinner. You can help by chopping the carrots."
And put in ear plugs and make dinner. If they don't want to eat what you've made they can make PB&J or wait till breakfast. Life is hard that way.
I'm not a very sensitive person when it comes to that. I am making an effort...if you can't make the same effort to make living life affordable and don't want what I'm making, then have nothing or have PB&J. He's a grown up...he'll get over it, or start to appreciate what you're making!
