First make fake buttermilk by adding some lemon juice to milk. You just want enough milk to dip your tomatoes in.
Next slice your tomatoes in 1/4 inch slices.
In a plastic bag add enough flour to coat all your tomatoes, garlic salt, pepper and Italian seasoning to taste (I do a couple of good shakes of each).
Then dip the tomatoes in the milk.
Then drop in the flour bag and shake and let sit for a couple seconds. I do this step in batches.
Then dip the floured slices in a whipped up egg and then in Panko bread crumbs. I like to flip the slices, press down and flip a couple times so I know they are well coated.
Finally fry in hot oil until golden brown.
Notes
I’ve made these for vegan friends by skipping the milk step and using Ener-G for the egg step
