Rinse tomatoes in cold water and pat dry.

If using Roma tomatoes, cut the tops off, and slice in half, if small. If larger, cut in half longways then cut in half again.

If using larger tomatoes, core, then quarter, and cut into small pieces.

Leave whole cherry tomatoes and grape tomatoes intact, removing any stems that may be in place.

Arrange with the skin side down and the cut side up (for quartered pieces) on the trays for your dehydrator.

Arrange tomatoes in a single layer on dehydrator trays

Sprinkle with a very small amount of kosher salt

Leave enough space between pieces

Use a silicone mesh sheet for small tomatoes

Set to a low temperature of 165°F
