Preheat the oven to 400°F. After this, Mix all the ingredients in a bowl. Season the mixture with salt and pepper, if necessary.
Prepare the tart by covering a sheet of parchment paper on a baking sheet. Place the phyllo sheets over the parchment. Drizzle melted butter between each sheet.
Place the filling on top of the last sheet of phyllo, leaving a border. The filling should be approximately 1 and 1/2 inches. Add the bell peppers. Mix the olive oil and salt. The oil should be used to coat the peppers.
Add tomato slices to the top and coat them with oil. Sprinkle dried oregano on top. To create a border, fold the sides of the parchment over. Sprinkle the border with sesame seeds and brush with the remaining butter.
Now Bake the bread on the middle rack for 45-50 minutes, or until golden.
