Last night I had some broccoli stems left over from dinner, so I cut them up, steamed them, and made a simple vegan gravy to serve them in. The dogs had this mixed in with their usual store-bought circle-shaped food and it was an even bigger hit than the store-bought canned food that I treated them to the night before (or the blueberries from the night before that).
One of my goals for this year is to start cooking more for the dogs. I saw some recipes yesterday in a book at my new chiropractor's office and I'm going to look into this more. I have two slow-cookers and I could easily be cooking for the dogs much more often than I do.
