Summers in Southern Italy as a child. I would look down my grandmother's balcony to watch her brother fan away the flies that swarmed over the tomatoes. Thinly sliced tomatoes orderly arranged in a single layer on a rack, drenched in salt and slowly soaking in the scorching sun.
You can even cure them afterwards! See here.
Thinly slice some sweet tomatoes. Quality is key here. I got some incredibly sweet San Marzo tomatoes, but cherry tomatoes are good too. Lay them on a single layer on a lined baking tray. Drizzle with a bit of oil and sprinkle with salt. Put it in the oven, and turn the oven light on. Leave overnight or as long as necessary until they're dried.
