• More and more people are interested in cooking,
  but busy lives often leave little time to plan
  and prepare meals.
• We are proposing a recommender system that will
  take into account preference, budget, on-hand
  ingredients, diet, and time constraints.
• The system can be used ahead of time to plan for
  dinner parties or on a moments notice for a
  quick dinner.
