Preheat oven to 350 degrees F.
Place the tomatoes in a medium bowl. Drizzle with 2 ounces oil and season with salt and pepper. Place seed side down on a lightly oiled baking sheet. Place in the oven and bake until the skins wrinkle and the tomatoes are soft, about 30 to 40 minutes.
Remove from the oven and cool. Peel the skins from the tomatoes and place in a colander over a bowl, to drain for about 20 minutes, occasionally pressing them to release juice. Reserve tomato juice for a later dish.
Heat 1-ounce of oil in a saute pan over high heat. Add in the onions and cook until translucent, about 3 to 4 minutes. Add in garlic and chiles and cook for 1 minute. Remove and cool.
In a medium bowl, combine the roasted tomatoes, parsley, scallions, oregano, and basil with the onion mixture. Add in the flour and bread crumbs and season with salt and pepper. Add more bread crumbs, if needed. Add sugar if tomato mix is acidic. Shape mixture into 2-ounce patties.
Heat the remaining oil in a medium skillet over high heat to reach 375 degrees F. Turn heat to medium-high heat and place the patties into the skillet in small batches. Cook on both sides until golden brown. Add more oil as needed. Remove patties and drain on paper towels. Season with salt while warm.
