Mix the flour, cornmeal and spices listed for the first layer and dip each tomato slice in it making sure it is completely coated.
Lay the slices on a large baking sheet and freeze for 30 minutes.
Crack eggs into a shallow bowl and blend with a fork.
In a second bowl combine the breadcrumbs, flour and cornmeal.
Dip each tomato slice in the egg and in the breadcrumb mixture. Make sure to completely coat the tomato and lay back on the baking sheet in a single layer.
At this point you can freeze the tomatoes in a single layer overnight and then place in a large ziplock bag.
Add oil to a cast iron skillet. The oil should be about 1-inch deep. Heat until shimmering (careful, it will be very hot!).
Fry until golden brown, about 1 to 2 minutes per side.
