If using a cauliflower mushroom, place it in a small pan and fill with boiling water. Simmer for 5 minutes. Drain, rinse with cold water, and drain again. Tear the mushroom into bite-size pieces. If using oyster mushrooms, add them in step 4 without blanching.
In a nonstick skillet or cast iron skillet, heat 1 tablespoon butter and all of the oil until sizzling. Add the filet mignon and cook, turning once, for 2 minutes per side for rare or about 3 1/2 minutes on each side if you prefer medium-rare.
Sear the edge of each steak by picking it up with tongs and rolling it around the pan. Place the steaks on a warm plate and loosely cover with foil.
Turn the heat to low, then add 1 tablespoon butter to the skillet and cook the porcini, chanterelles, girolles, and oysters, if using, for 3 minutes.
Add the garlic, stir, and cook for 2 minutes, then turn the heat up and carefully add the cauliflower mushroom and brandy. Cook for 1 minute, then add the truffle shavings, if using, and parsley and season with the salt and pepper.
Transfer the steaks to plates and top with the mushroom mixture. Season with pink peppercorns, if desired, and sprinkle with parsley.
