I developed this system by watching the Deal a Meal commercial! LOL!
Honestly, now I can plan a week's worth of meals and make out my grocery list in 10 minutes! No lie! And we have multiple food allergies in this house.
I bought some index cards. Then I wrote down our favorite meals, one on each card. I did NOT write the RECIPE on the card, I just wrote where to find the recipe (which cookbook, which page). Then I wrote down the ingredients. I also put down sides that go with the recipe like potatoes or rice.
I'm a sharpie addict so I color coded the recipes (slow cooker, grill, fast meals). You don't have to do that.
To make out my meal plan I just need to look through the cards. I write the meals on a dry erase calendar. To make out my grocery list I only have to look at the cards to see the ingredients needed. It really only takes 10 minutes!
I have cards for my daughter's meals and cards for my meals since we are allergic to different things. Sometimes I make 2 meals, or I make the same meal but I separate the portions and make sure one doesn't contain an allergen.
I only made out 14 meal cards to start with (two weeks).Then every week I search for a new recipe to try and I add it to the cards. I started with 14 cards but now I have many! I did not want to "crash and burn" by trying to do too much at once. Baby steps, y'know?
It's funny, now that I do this my husband or daughter will find a recipe or taste something good at someone else's house and tell me to "add it to the cards!" LOL!
I enjoy adding one new recipe a week, but now that I have more cards I don't always do this. Sometimes I'm in a hurry so I just shuffle through the cards and quickly pick something out!
I also have an iPod app that makes a grocery list. So the ingredients I buy regularly for these recipes are already in the database and I just click them to make my grocery list! What I like is it categorizes them according to the aisle in my grocery store so I just zip through the store, aisle by aisle, and toss things into my cart.
I really hate meal planning and grocery shopping so now I'm happy that I can do them quickly and efficiently and then get on to better things!
Hope that helps!
P.S. Don't forget to write down "easy" meals like hot dogs or mac and cheese. The point is you want to look at the cards without having to think! I'll often come across my "hot dogs" card, and even though the ingredients are "package of hot dogs and buns" it reminds me of a quick meal for those busy nights!
