Lay out the tomato slices in a single layer. Sprinkle a pinch of salt on top and let it sit for 15 minutes. In the meantime, add the cornmeal, panko, paprika, garlic powder, and onion powder into a dish. Mix until the ingredients are combined. Add the flour into a separate dish and mix it together with a pinch of salt and pepper. Add the heavy cream into a separate dish.
After 15 minutes, pat both sides of the tomatoes dry with paper towels. Pour about 1 inch of vegetable oil in a pan with sides. Heat it over medium high heat until it reaches 375℉.
While the oil heats, dredge each tomato slice into the flour until fully coated. Dip the tomatoes into the heavy cream until all of the flour has been absorbed. Then add the tomato into the cornmeal panko mix. Press the breading onto both sides of the tomato until well coated.
Add the tomatoes into the hot oil, being sure to not overcrowd the pan. Cook for 2-3 minutes on each side until golden brown. Remove the tomatoes from the oil and place them onto a plate lined with paper towels to drain. Season the tomatoes with a pinch of salt.
Toast the slices of sourdough in a pan or in a toaster. In the meantime, add the ribboned zucchini into a bowl along with the olive oil and a pinch of salt and pepper. Toss everything together until combined.
Spread the pesto onto one slice of sourdough and spread the mayo onto the other slice. Add some of the arugula onto one of the slices of sourdough. Then layer on a few slices of fried green tomatoes. Spread the stracciatella onto the tomatoes. Season it with salt and pepper then drizzle olive oil on top. Add on a few basil leaves and a portion of the ribboned zucchini. Top with the remaining slice of sourdough. Repeat this process to assemble the remaining sandwich. Slice in half and enjoy!
