Suggest Dinner

Trying to make this as a not too small but not big coding exercise that I can solve with many languages and experiment things.

From the ingredients you have, suggest tonight's dinner

$ suggest-dinner --recipes recipes.yaml --stock stock.yaml
Beef steak

• stock.yaml

version: 1
ingredients:
  - onion
  - beef
  - potato

• recipes.yaml

version: 1
recipes:
  - name: Pot-au-feu
    ingredients:
      - onion
      - leek
      - pork
  - name: Beef steak
    ingredients:
      - beef

Additional challenges

• Return not just one but all recipes that can be cooked
• Amount for ingredients (both stock and recipe)
• How many serves
• Ingredients can expire
• Each recipe has different difficulty
• Each recipe has different time to cook
• Read recipes and/or stock from different file formats (JSON, CSV, ...)
• Read recipes and/or stock from DB
• Make it a web service (provide API)
• Course menu: Entre, main, ...
• Food genre (Japanese, Thai, French, ...)
• Ingredients at hand, ingredients that can buy (with cost)
• Data migration (schema change)
• Provide a command if certain recipe can be cooked, if not, tell why
