One of my favorite frugal meal(s) is buying a cooked rotisserie chicken from a local grocery store. Not only is it yummy, but it usually only cost less that $8 for a whole chicken. We eat it fresh from the store, I especially love the skin and dark meat. Afterwards, pull apart the left over chicken and set aside for later.
Most people would throw away the bones, but they are what makes the best chicken soup! If you don't already have one, I highly recommend investing in a slow cooker or crock pot. We found ours in a thrift store for just $10. Throw in the rest of the chicken - bones and all in the crock pot, add water. Let it cook until the bones falls apart. Once cooked, make sure to remove the bones then add seasoning, veggies and anything else you want.
I've stretched an $8 rotisserie chicken into 4 different meals for 2 people. Now that's frugal eating!!
Meal #1 - Chicken wings, drumsticks (mostly dark meat)
Meal #2 - Stir fry chicken (1/2 of leftover white meat)
Meal #3 - Chicken salad (other half of leftover white meat)
Meal #4 - Chicken soup (makes up to 4 bowls of soup)
I'm sure, there are a hundred more ways to get creative with leftover rotisserie chicken. Bon appetite!
