You can really get your moneys worth out of a rotissary chicken or a homemade roasted chicken!!!
I use the leftovers for:
Chicken Alfredo (just get you some cheap alfredo sauce and pasta and that shouldn't be so expensive - then add cut up chicken to it!)
Soups - you can really make some amazing soup recipes with some cheapo egg noodles and leftover chicken! Check out some online recipe websites- there are tons of great meal ideas out there for different soups and you can really use up a lot of what you have in a soup!
BBQ Chicken Pizza - get you some pizza shells (they're cheap and usually come in a 2 pack at the store) and a jar of your fav. bbq sauce then coat the crust in some EVOO, your fav bbq sauce and add your leftover chicken and some shredded cheese- this is such a yummy pizza and a lot cheaper than ordering one!
Chicken quesadillas (Tortillas are cheap and can really go a long ways- add a little butter to the inside of the tortillas, then shredded chicken and shredded cheese and just cook it in a frying pan- voila!)
If you have leftover Rotel dip- you can add your leftover chicken to it and also some spaghetti and you have chicken rotel- it's soooo yummy!!! It's a family favorite and a great way to use up two different leftovers!
I also like to use leftover chicken in salads - you can really have a nice meal out of a chicken salad! It's healthy and inexpensive
You could also use your leftover chicken and get some rice (it's always cheap and always feeds a lot of ppl!) and make you some chicken and rice (add a little chicken broth and seasoning) or you could do a nice stir-fry with it depending on what seasinings/sauces you have around the house. Save those leftover Soy sauces from when you go out to eat- I can always use those up at home!!! I use them to season a lot of different things with!
You could also use the leftover chicken and get some tortillas and you could have chicken tacos
There's sooo many things you could do with a chicken- they're really worth the money and can be stretched for numerous meals
Same with pasta and rice- just be careful not to go too crazy with all the carbs. They make affordable/healthy whole wheat versions of most stuff nowdays - cheap and healhy in moderation!
The big rolls of ground beef are great too- you can get soo many meals out of them and really feed a lot of people with it- spaghetti is always a good cheap meal!
