I heart leftovers. But I know not everyone does. Maybe it's because many people think of leftovers as eating-the-same-meal-every-night-for-a-week. But I'm going to try to change your mind. It's easy to transform certain leftover ingredients into completely different dishes if you think a little creatively. And using leftovers can help you save money and avoid waste. Here are yummy recipes-many of which are from our new book, EatingWell on a Budget-to help you rethink your leftovers.

A lot of people have Pasta Night once a week just like we do. Cooking double the amount of spaghetti takes no extra time and becomes the basis for dinner tomorrow night.

Love Your Leftovers: Make Spaghetti Frittata. Here's a creative way to use leftover cooked spaghetti: try mixing it with eggs for a filling Italian omelet. If you don't want to buy separate bunches of fresh herbs, look for an Italian blend package that may contain some of each or use one-third the amount of dried herbs.

Roast Chicken
Why roast one chicken when you can roast two in about the same amount of time? I cut-up the leftover meat into bite-size pieces and freeze it in 1- or 2-cup portions so I can easily add it to soups, stews or whatever suits my fancy.

Love Your Leftovers: Make Crispy Chicken Tostadas. Shredded leftover chicken or turkey tops homemade tostadas in this Tex-Mex favorite. Making your own tostada shells from fresh corn tortillas is easier than you might think-crisp them up in the oven while you prepare the toppings. Get the recipe plus casseroles, soups, sandwiches and salads to use your leftover chicken.

Mashed Potatoes
I love love love mashed potatoes, so I often make too much. I love to tuck leftovers into a weekend-morning omelet with crumbled bacon and shredded Cheddar (yum!), but mashed potatoes can be of good use in other ways too.

Ham is a popular Sunday dinner for some-one that often produces lots of leftovers. Just as I do with chicken, I like to dice up leftover ham and freeze it. It adds loads of flavor to any recipe you put it in.

Love Your Leftovers: Make Ham & Swiss Rosti. Rösti is a traditional Swiss potato pancake typically served as a side dish, but we added ham and cheese to transform it into an easy weeknight supper. Get the recipe, plus more ways to enjoy ham.
