Preheat the oven to 350°F.
Cut the tomatoes in large slices about 1/2 inch in thickness (or in half if the tomatoes are small).
Combine all the other ingredients in a food processor and blend until mixed well.
Line a baking sheet with parchment paper and lay out the tomato slices on the paper. Spread the mix on the tomato slices and bake in the oven for 30 minutes.
