Add Olive Oil (2 tablespoon) onto a saucepan over medium-high heat. Place the Brussels Sprouts (12) cut-side down to let them caramelize.
Season with Salt (1/4 teaspoon) and Ground Black Pepper (1 pinch), then drizzle more Olive Oil (1 tablespoon) over the top and sear for several minutes.
Add the Bacon (6 slice) and cook until they're slightly crispy, then turn the sprouts over and stir around. Lastly, add the Onion (1/2 cup) and cook until the onion is soft.
Lower the heat and add Gouda (1/2 cup), Feta Cheese (1/2 cup), and Sour Cream (1/2 cup). Mix well, and cook for another 4 to 5 minutes or until heated through.
To serve, you can plate this up family-style or use it as a side dish to roast chicken or another protein. Enjoy!
