Eating out of the Pantry

I noticed on some other Blogs that frugal moms were trying to save money by eating only what they have stored in their pantry for one whole month.  They only go to the grocery store for fresh dairy and produce once a week.   We really need to catch up some bills this month so I decided to try it.  Here is what I want to do:
1. Eat out only two times a week until the end of March (baby steps, we eat out a lot!)
2. Spend only $100 on groceries until the end of March (about $100.00 less than average)
3. Eat out of the pantry/freezer as much as possible.
Tonight I dug through our freezer and found some frozen hamburger meat that I had made into a basic meatloaf mixture before I froze it.  I browned it instead of forming it into a meatloaf. I found some whole wheat noodles and had a plan!  I cooked the noodles and mixed with a can of diced tomatoes, a can of tomato sauce, a little water, some Italian seasoning and 2 cups shredded cheese (also from the freezer).  Added the cooked hamburger mixture.  My family seemed to really enjoy it, it was kind of like chili mac, I guess.  I also made a can of peas.  Pretty proud of myself, I usually never try things without a recipe.  Well tomorrow is my daughter's 17th b-day and I told her we would take her out. I think I will use up some day old bread to make french toast in the morning instead of offering to run out for donuts or catching McDonalds on the way to work.  It's Spring break for my husband and kids but I only took two days off so I will go into work for a bit tomorrow.  If you want to try this pantry thing with me, let me know we can share ideas!
