I keep 2 cup pyrex containers. Most things I cook in a crock pot or baking dish, I make extra. We put the leftovers in the pyrex containers. They can usually stay in the refrigerator for a week or in the freezer for longer. Then leftovers work for lunches or when a family member is eating alone because the rest of the family is busy.

Some of the things I do this with are smoked turkey leg soup, salsa meat (chicken, pork, beef, or elk) casserole, seafood bisque, keto gumbo, jalapenYum, etc. I don't eat these things anymore, but we will also do the same with homemade mac & cheese with sausage & broccoli or spaghetti and meatsauce with veggies.
