Heat the Skillet: Warm a non-stick skillet over medium heat.
Butter up the Bread: Slather on good slathering of butter onto 1 side of each slice of keto bread so you get a golden, crispy, crust.
Assemble the Sandwich: Layer cheese slices between the unbuttered sides of the bread. Add optional seasonings like garlic powder or herbs.
Grill the First Side: Place the sandwich on the skillet, buttered side down. Cook for 2–3 minutes until golden brown.
Second flip and grill: Flip with care and cook the other side until cheese is completely melted.
Rest and Serve: Allow to sit for 1 minute before cutting and serving.
