Take a lactaid pill before you try this (I do at least):
First, grate romano cheese and/or parmesan, a little garlic (minced), pepper and parsley (this will be for the outside);
Next, shred chedder, monterey jack, and swiss (optional), and blend by hand;
Butter thick slices of sourdough, and place on cast-iron skillet, butter-side down;
Place a thin ‘sheet’ of the cheddar, monterey jack and swiss on top of the non-buttered sides (the sides facing up);
Fold one slice on top of the other; place romano/parmesan, garlic, pepper and parsely on the butter top, and flip immediately (this will be the “A” side of the sandwich that cooks first); after flip, repeat the top spread for the “B” side.
As soon as you start to see slight “gooing” of the middle cheese layer, flip, and press down once with spatula to even out;
Garnish with pickles, tomato, red onion, dijon mustard, and olives on the side.
p.s. another great recipe for a grilled sandwich (NO CHEESE) is to grill Peanut Butter and Jelly on Sourdough (Bread, PB n J, and butter only). It’s the best of sweet and salty in one! Now on to the gym you go!
