Cleaning out the pantry/fridge/freezer

I am challenging myself in the month of May to eat out of the pantry/freezer/fridge. We have so much stuff that needs to be used up so I decided this is the perfect month to do this. It doesn't hurt that we will be in Washington DC visiting my sister for a week!
First, I made a list of everything in the freezer and pantry. Then I made my menu for the MONTH-yes, the entire month-based on what we have on hand. Finally, I am making a list of the few things that we need to make the menu work. So, I know that I am picking up some shredded cheeses, some ziti noodles, and some ground beef. And every week I will pick up milk, eggs, bread (if we need it since I have 3 loaves in the freezer), and fresh produce. My goal is to spend less than $200 for the entire month on groceries, toiletries, etc. Wish me luck! I will keep you posted
