I am roasting veggies from my garden -- lots of heirloom tomatoes, peppers, egg plant, and garlic. I use some herbs and good extra virgin olive oil. They reduce down a lot, so it is easy for me to freeze them in small plastic containers. This makes wonderful sauce over baked potatoes, rice, meat, fish, etc. all winter. I can things too, but this is easier, and I like the flavour better when things are frozen.
