Preheat the skillet: Heat a skillet over medium heat to prepare for grilling the sandwich.

Butter the bread: Generously butter one side of each slice of sourdough bread. This will give the sandwich a deliciously crispy and golden crust.

Assemble the sandwich: On the unbuttered side of two slices of bread, layer a slice of cheddar cheese. Then, add two slices of crispy bacon, several slices of ripe avocado, and top it off with another slice of cheddar cheese. Place the other slice of bread on top, with the buttered side facing up.

Grill the sandwich: Place the assembled sandwich in the skillet. Press down lightly with a spatula to ensure good contact with the pan. Grill for about 3-5 minutes on each side, or until the bread is golden and crispy and the cheese is melted and gooey.

Repeat the process: Repeat the same steps for the second sandwich.

Serve: Once both sandwiches are grilled to perfection, remove from the skillet and slice them in half. Serve immediately while they’re warm and melty!
