Blend strawberries and 1 can of lemonade concentrate together. Do not add water. Blend until all the strawberries pieces are turned into liquid and there are no clumps
Lightly oil your jelly roll or baking sheet with olive or vegetable oil. I smear it on with a towel to get a light coating.
Dehydrate in oven or dehydrator for 3-4 hours at 160 °F. Times can be different for how thick you poured your fruit leather. The thicker it is, the longer the dehydration process.
Lightly touch the fruit leather, if it does not stick to your finger then it is finished. Take out and let cool completely before cutting into pieces. If it is crispy and brittle then you have over "cooked it".
