eat out of your pantry and fridge/freezer

we all have a tendancy to buy up good deals and store them.my tip is:
instead of saying I want to fix this for supper tonight/breakfast/lunch and going to the store for part or all of the ingredients – look and see what you have in your fridge/pantry that might go to waste if you DONT use it.think of ways to reuse that leftover whatever so it looks new to the hubby and kids,not like leftovers.think of ways to save money by using what you already have.example-last week i had company for a few days and made a roast from a buy one get one free sale.the following day we had beef potpie with homemade crust and homemade bisquits,the bisquit mix was bought from the local bent and dent store.five pounds for 85 cents!all i had to add was water.
