For many people, the main reason for meal prepping is convenience. By preparing meals in advance, they can save time during the week when they are busy with work or other commitments. Instead of spending time each day cooking, they can simply reheat a pre-made meal and enjoy a nutritious, home-cooked meal without the hassle.
This takes the stress out of always wondering what you will make for dinner. It provides an environment where everyone can sit down to dinner together but they do not have to eat the same meal. Much like you have options at your favorite take-out place. Meal prep can be a solution for picky eaters or those with specific dietary needs.
