I've got a clipboard in the kitchen in a convenient spot for me to see and reference when I'm in there.
On the clipboard is my dinner planning paper. I plan out the meals for 2 weeks and what ingredients I need to buy. There's room on the list for dinners and desserts, then I look through the pantry and what's I've got on hand and write out the ingredients I need to buy on the paper, so I've got my shopping list all ready. To keep things simple, I try to just do grocery shopping on one day (Thursday works nice for me), and I usually just go to Walmart and Costco. I look through whatever recipe books and then choose the dinner and dessert recipes to make. I write the meal and then reference it with book and page number so I can find it when it's time to make dinner. For example "Lime & Honey Salmon, Ray #253" for a recipe in a Rachel Ray's cookbook on page 253. I also have my own recipe book for recipes from online or from magazines that I print up and organize -
Those are referenced by tab and page #.
I keep a sheet for next week on the clipboard too, so if there's a meal I know they kids want next time I can write it in, and I write down anything else we need from the store on there.
One month into it and it's working so far! We've had a sit down dinner ready everynight. :)
