Has it happened when you suddenly make a change to your regular routine and find yourself wondering, "Why the heck you didn't do this before?!" I seem to be having continual epiphany of sorts past 2 years. May be a baby thrown into the already chaotic lifestyle did it but oh boy - AM I GLAD!!! While routines are great enabling you to go about doing your chores mindlessly, I find it prudent to stop once in a while to see if you can make a smart tweak to it. Like freezing cooked beans for example. Since I use a pressure cooker, making a batch of beans was never a cumbersome process until I discovered making a huge batch and freezing them. Life just got way simpler. With Instant Pot, cooking dried beans (BIG BATCH) became a child's play and freezing was only one step away.  These lasts for months (around 6 months) in the freezer. I usually make a big batch of different beans and freeze to see me through 1-2 months and can enjoy them without moment's notice. For a vegetarian, these are especially a boon for protein and also to add variety to regular meals. Make a big batch of beans of your choice - using Instant Pot or your regular method. Drain the cooking water. I usually save them for making stocks, soups or stews. Let your beans cool down. If you are in a hurry, you can always rinse them under cold water to cool them down quickly. Transfer them into freezer safe containers. Out of many different options I have tried - glass, plastic, silicon bags - I find these ziplocks to be the most convenient and hence opt for them (until I find something better). The amount to freeze will depend on your usage pattern. If you tend to use cans/equivalent amounts, you can transfer 1-3/4 cups of beans (or as needed) in separate bags and store them. You can simply zip and store them as it is. I like to place it flattened as shown below to make stacking easier in the fridge. Real estate in my freezer is pretty expensive. While not strictly necessary, I find vacuum sealing helps prevent crystals that cause freezer burn. You don't really need a fancy equipment to do this. Just a humble straw. I close the bag leaving a slit just big enough for the straw. Now I suck out the as much air as I can - you will see it tightening and immediately close the bag all the way.  It needn't be perfect. Doing this also helps stacking easier. All done! Now you have one less chore to do in the kitchen for the rest of the weeks and more savings.  Nutrition at times can be cheap too :)
