I posted earlier today looking for some menu software.

Thanks to halcyon_n_on , I've found it.

Input your own recipes, and with a few clicks it will output a full weeks menu for you, selected from those recipies.  You can then change any meals you like, and when you're ready to go export a shopping list.

And the cost?  $10, payable over paypal.

Perfect.  Thank you all much for your help!
