Heat avocado oil in a large cast iron skillet over medium to medium high heat. The temperature of the oil should be between 350℉ and 375℉ while frying the tomatoes.
Set up the 3 bowls for a breading station. In the first bowl=flour, second bowl= eggs, third bowl= bread crumbs, garlic powder, sea salt, and pepper.
Once the oil is hot, dip one tomato slice at a time into the flour, then egg, then breadcrumb bowls.
Carefully place the breaded tomatoes into the hot oil and cook for about 1-2 minutes per side or until golden brown. Place the cooked tomatoes on a paper towel lined plate and continue the batch.
