Preheat your oven to 350 degrees. Take some Roma Tomatoes, cut the stem end off and then cut the Romas into thirds lengthwise.
Lightly oil or spray a baking sheet and then lay out the roma slices. A thin layer of olive oil (or cooking spray) and then place a little bit of sea salt on each slice.
Then finish each slice with a couple of pieces of frech diced basil. Place the whole thing in the oven and let it sit there for 1 1/2 to 2 hours. Remove from the oven, let cool and then store or just eat them warm from the oven.
