Why are there different meals on the family and individual plans?
The dinner-only family meal plans don't have leftovers, whereas on the individual plan, sometimes you make a soup and have it twice for ease. Also, individual plan recipes are not suitable for families (you can't just multiply a recipe out without some complications) and similarly, the family recipes make way too much for an individual, unless they want to eat the same thing for four days.
The plans do sometimes have similar or the same recipes, but since 1 person vs. 4 people is so different, we can't make the plans or meals the same or identical. That's why we have the two different plans, to accommodate every household.
