Great question! It depends on if you want meals for lunch and dinner for just the work week or the entire week. The 14 meal plan comes with 14 individual serving size meals. So 1 person can use it for lunch and dinner for the entire week, or 2 people can use it for lunch (or even dinner) for the entire week. If you only need for the work week, then the 10 meal plan is the one for you!
