Suggest an alternative dish in the nutrition plan based on macros, goals, and allergies

Customers can click an 'Alternative' button in the nutrition module next to a planned dish. The system then suggests a replacement dish with similar macros, tailored to the customer's goals, allergies, and preferences. For example, a customer who doesn't feel like quark with fruit can easily switch to an alternative such as a sandwich with chicken breast and egg, without the schedule becoming unbalanced. Additional feature: allow a customer to replace a single ingredient as well. Automatically convert the required amount of the alternative so that the calorie and macro goals of the meal remain consistent.
