Pot roast is about the easiest dinner on the planet. Throw it in the slow cooker in the morning, eat it when you get home. Or start it on the stove when you get home, check on it every half hour, and eat three hours later. What's with making it into some symbol of women's subjugation? All you're demonstrating is that you can't cook. And why be proud of that?
I posted before I saw yours; you're verifying how easy a good pot roast really is. I'm betting this will make her curious about trying one.
Is there any better smell to have in the house when you open the door at night? :-D
