Query: Great concept and easily scaled down if you're single

This is an excellent alternative to just eating the same old leftovers the next day. The genius of this cookbook is that by planning for leftovers, you end up spending less and wasting less food & money. They're easily scaled down to 2-serving versions (all the recipes make 4 servings) if you're single or a couple. I also like that the leftover variations are very different than the original meal or each other, so you don't get bored with what you're having. I disagree about the recipes being too fancy. A few of them are true special-occasion meals, but by and large, the ingredients are easy to find and the recipes are quick to prepare. In fact, my only complaint would have been that some of the recipes could have been spiced up a little: they're yummy but sometimes a little plain.
