Each night when I clean up after dinner, I make sure that I have things underway for the next night's dinner. I make sure that I know what I am planning to make and I double check that I have all ingredients. If something needs to be taken out and defrosted, I get that done.
Sometimes it can be hard to plan a week's meals in advance. Even if you do it, your plans might need to be adjusted. By double-checking your plan the night before. You will be ready to go for the next evening. This helps me deliver good meals to my family each night.
