To summarize, students choose between a variety of entrées that include a protein and grain component. They then choose from an assortment of fruits, veggies, and milks.
Students can choose whatever they want and will be charged accordingly, but if they want the "meal" price from the state*, they must have at least three components--one of which must be a fruit or vegetable.
If they follow the three components/one of which is fruit/vegetable, that is a "reimbursable meal" and they get charged the meal price (in some student cases, that would mean it is free).
If they do not follow these requirements, they simply get charged normal pricing for each item chosen.
