I have been making twice the serving needs and freezing a whole meal for later. I have also done some of the recipes that Daisy had that you can pressure can for later.
There is a resource I have been looking into: Once a Month Meal Plans. They give you recipes and you prep one for cooking now and freezing everything you need for another night. I have done it a couple of times, so easy. I have done a few that I can make up quick in my instant pot but there are other ways to cook them also.
