Prepare a skillet with cooking spray (cast iron works best). Heat skillet over medium heat.

Butter one side of each slice of bread. Flip the bread over and spread the pimento cheese on the other side.

Place two layers on fried green tomatoes on two slices of bread. Season with salt and pepper, if desired. For added cheesiness, spread additional pimento cheese between the tomato layers.

Top with remaining slices of bread.

Carefully place sandwiches in the hot skillet. Grill until bread is brown and toasted. Carefully flip and toast the other side until bread is brown and the cheese is gooey.

Remove sandwich from skillet. Cut in half.
