In attempt to use and preserve all the tomatoes I bought on sale I decided to "sun dry" some. I really had no desire to leave the tomatoes outside and let the cats that roam eat them so I found a way to dry them in the oven.
Cut Roma tomatoes into quarters. You can also try this with cherry tomatoes cut in halves. Place cut tomatoes on a baking sheet. Sprinkle lightly with coarse salt. Place in oven at 175F degrees for 8 hours. Larger pieces may require more time. Store in a glass jar filled with olive oil to cover tomatoes, or in a plastic container in the refrigerator for non-oily tomatoes. You can also store these in the freezer.
