For either the first two meals of the day during the work week, or dinner four days a week. I just ordered Mark Bittman's book - and I'm hoping it will inspire me. The thing is, we participate in a CSF, as well a meat CSA which provide us with sustainably raised/caught meat and fish. I feel very little guilt when it comes to where my food comes from, I just think it would be a great exercise in cooking/eating.
The issue is the work I do is all things food, and it's very hard to sustain any sort of diet when you are either constantly eating, or constantly cooking.
That being said, I need to go on a diet of some sort.
