Place the tomatoes in a single layer on paper towels and salt lightly. Let sit while you prepare the breading.
Place the flour in a bowl and season with salt and pepper. Mix together. Place the eggs, milk, salt and pepper in a second bowl and whisk well. Place the cornmeal, sage, thyme, oregano, green onions, salt and pepper in a third bowl and mix together.
With paper towels, dry the tomatoes. One by one, place the tomatoes in the flour first, tapping off the excess. Next dip the tomato in the egg to coat completely. Then dip the tomato in cornmeal and tap off the excess.
Heat half of the olive oil in a large frying pan over medium heat until rippling. Cook the tomatoes in a single layer until golden on each side and the wall of the tomato is fork tender, 10 to 12 minutes total. Remove from the pan and drain on paper towels. Repeat with the remaining tomato slices.
To serve, place the tomatoes on a plate. Garnish with the herb sprigs and serve with mayonnaise.
