With having to feed 3 growing boys, and my hubby, meal planning is key to saving money. I plan and fix new meals on Monday, Tuesday and Wednesday evenings. It may be crock pot meals, grilling out in the summer, dinners I've prepared ahead, frozen and can easily bake etc. Thursday is then known as "buffet night" at our house where we heat up all the extras from earlier in the week and each person can have what they would like. By eating everything from earlier in the week it allows me to clean out the fridge every Thursday and I'm ready to go to the store on Friday:)
Our family also enjoys bon fires in our backyard. On Sunday evenings when we are home and the weather cooperates we will have our dinner over the fire ~ hot dogs, pudgy pies, smores etc. As we eat pretty healthy during the week the occasional bon fire night feast isn't tooooo bad for us:)
