In a large bowl, combine panko, bread crumbs, cornmeal, flour, salt, pepper and cayenne, mixing thoroughly to combine. In a small bowl, lightly beat the eggs. Take each slice of green tomato and coat it in the beaten egg, then dredge it through the bread crumb mix, pressing on both sides to adhere. Gently place the tomato on the wire rack and repeat with the remaining slices. Once finished, spray each tomato with olive oil (or non-stick spray, whatever you have). Bake for 25-30 minutes, until tomatoes are crispy and golden.
