Here are some tips that will help you to save some money when planning your meals.
Write a Shopping List
Plan your menus one or two weeks ahead and write a list of ingredients you need to buy. Always check your pantry first. In the store, stick to your list.
Scan Through Weekly Ads and Coupons
It is helpful and can save you quite some money if you buy things when they are on sale or if you have a coupon for them. Plan your meals accordingly or freeze them. But be careful: You do not need everything that is in a flyer and you do not need endless stocks.
De-clutter Your Fridge, Your Freezer and Your Pantry
Is your fridge stuffed with half empty bottles or jars of salad dressing, soy sauce, barbecue sauce, etc? Are there some frozen chicken breasts left in your freezer since a couple of weeks? Do you still have some split peas when the summer starts? Do not wait until the best before date expires. Be creative and think of meals that ask for those ingredients and use them. Here is an example. Integrate those meals in your menu plan right away before you forget them. You will be surprised how well organized and clean your fridge and freezer soon will look like.
No Instant Meals
Try to avoid ready-to-serve meals or meals from a package or a can. Those are expensive and do not always contain the ingredients you want. Learn how to cook some basic recipes and you will be surprised how easily you can create new variations of those.
Fruit and vegetables taste best and and are well-priced when they are in season. If you really need raspberries at Christmas pick some in July and freeze them.
