Wash the lettuce leaves well and shake/pat them dry.
Crumble feta cheese, slice the Smoked Cheddar and set aside.
Butter one side each of the sourdough slices.
Assemble all the ingredients before you start.
Place a non-stick pan on low heat and add a pat of butter.
As the butter begins to melt, place a slice of sourdough on the pan.
Layer with lettuce leaves, tomato slices and cheeses.
Season with freshly ground black pepper.
Top with the second slice of sourdough bread and cover with a lid.
If you don't have a lid, use a heatproof plate and press it down using a heavy object.
Cook for a minute or two, until the bottom slice is golden (do the corner lift test here).
Flip over, add another pat of butter and cook the second side as you did the first.
Once done, remove from the heat, slice into two or just bite in!
