You can make dried tomatoes yourself. Cut Roma tomatoes in lengthwise halves, or slice ripe regular tomatoes into half inch slices for drying. Next, lightly salt the open sides and place them salt-side up on a wire cooling rack.
Use a cookie sheet to hold the rack and set it in the oven at 190 degrees for at least 10 hours. You can store your dried tomatoes in a plastic bag in the freezer. You can put the dried tomatoes with fresh herbs in a jar with olive oil to preserve them.
Put your canned tomatoes in the fridge and be sure to use them in the next two weeks.
