6slicesbacon, (I use center-cut; thick cut is nice, too)
8slicessourdough bread
8ouncesmonterey jack, shredded on a box grater
2green onions, thinly sliced
3tablespoonsmayonnaise, (regular or light; use Kewpie if you've got! You may not need all 3 tbsps.)
2tablespoonstoasted sesame oil
Instructions
Place the bacon slices in a heavy bottomed skillet (cast iron is ideal) over medium heat. Cook until crisp, then transfer to a paper towel to drain. Cool slightly, then roughly chop.
Add the chopped kimchi to the bacon fat in the skillet. Cook over medium heat for 3-4 minutes to caramelize. Mix the chopped bacon and sesame seeds into the kimchi to combine. Remove to a plate, and turn off the heat. DO NOT wipe out the skillet.
Layer the sandwiches like this: sourdough, 1 ounce of cheese, 1/4 of the kimchi-bacon mixture, 1/4 of the sliced green onions, another 1 ounce of cheese, last slice of sourdough. Spread a thin layer of mayo on the top and the bottom of the sandwiches.
Toast the sandwiches in 2 batches: add 2 teaspoons of sesame oil to the skillet and return it to medium-low heat. Once hot and shimmery, add 2 of the sandwiches. Cook for 3 to 5 minutes per side; adding another teaspoon of sesame oil when flipping. Remove to a cutting board and repeat with the other two sandwiches. (You can keep the first batch warm by placing them on a sheet pan in a very low oven.)
Slice in half + enjoy!
