Buying groceries and putting them away is a biggish task. And when you're done, you're tired of looking at food and thinking about all the prep work of cooking food. But most of what you have isn't food yet, it's still ingredients.
You deserve to have that one ready dinner tonight, whether it's pizza or rotisserie chicken or sushi or Greek-salad-inna-box or rat-onna-stick. You know you'll do it anyway, so just plan it in as you shop.
