You go Patrice!
For us "shopping" is a separate stage -- sort of like fabric collecting, once you have a collection you make something out of it. We've always viewed shopping as a necessary but reasonably enjoyable "us" time. Not to say we don't go solo too. But shopping usually involves leaving the house, and ends when groceries are put away.
I often do quite a bit of prep work as I'm unpacking, but for me cooking begins when I have to start chopping or washing stuff or otherwise using some sort of pan.
I've found in my times of limited vision and depression that I am better off spending money by pre-prepped vegies and things like grated cheese or sliced mushrooms. I used to do the all of that sort of thing, but now I'm generally worn out just by the shopping not including the chopping!
I don't get to bake much
I used to do something, usually bread, maybe something sweeter at least weekly for a long time (when my oven broke maybe 10 years back at the old house??). Even when neither of us were eating the goodies, we used to send them to the hubby's work. Now that we have a working oven and a new job, I might be able to do that again and get some goodies out of my system! I love baking and still watch Great British Baking Show and others, but me and carbs just don't get along so much any more.
