Spaghetti  is the perfect dish to meal plan as you can make a large batch of the sauce and then heat it up and toss it with freshly boiled pasta for a meal that can be assembled in under ten minutes. One batch of this is enough to make 2 large servings, so just multiply the sauce ingredients for the number of people you're feeding and the number of meals you want it for. Be aware that if you increase the amount significantly, the caramelization and simmering steps may take a bit more time.  Once the sauce is done, just divide it up into the number of meals you want to have it for, and then refrigerate the portions you want to eat within the next few days, and freeze any portions you want to eat after that. Then you just have to defrost the sauce (either in a microwave, or in a pot covered with a lid), boil the pasta, and toss the two together.
