Mix cherry tomatoes, oil, and salt together in a bowl. Then place the cherry tomatoes (sliced side up) on food dehydrator trays.

Dehydrate at 135 degrees over night or 7-8 hours.

When tomatoes are dried they can be stored in either a plastic bag or packed in a jar with olive oil.  If storing for long term, add a 1/2 cup of white vinegar or red wine vinegar to a bowl. Dip tomatoes into vinegar, just for a second, shake excess off, and then store in jar with oil.
