Mix 4 tablespoons of softened vegan butter with 2 cloves of minced garlic and 2 tablespoons of fresh chopped parsley. Set aside for later.
Marinate the king oyster mushrooms
Mix 2 tablespoons of hot water with 1 tablespoon of oil, 1 teaspoon of kelp flakes, and 1/4 teaspoon salt in a shallow dish.
Wash the king oyster mushrooms in cool running water to wash off any dirt or debris. Then, with a sharp knife, cut off the brown section at the top of the mushroom stem and the hard section at the bottom, then slice the stem into rounds about 1/4 inch thick. Cut crisscross diagonal lines across the rounds about halfway through to allow more marinade to soak into the mushrooms.
Place the mushroom slices in the marinade and let them sit for at least 15 minutes. You can put them in the fridge and let them sit for up to 3 hours before sautéing.
Cook the scallops
Heat a large skillet with 1 tablespoon of oil over medium-high heat. Drain the liquid marinade off the mushrooms. Once the pan is hot, add the marinated king oyster mushrooms to the hot oil and cook for about 3-4 minutes on each side before flipping.
Once cooked on both sides turn off the heat and add the vegan garlic butter and the juice of 1/4 a lemon to the pan.
Salt and pepper to taste, and garnish with fresh parsley and lemon wedges. Serve over rice, quinoa, mashed potatoes, risotto, or pasta.
Notes
If you use nori sheets instead of flakes, you can put them in the blender and pulse it a few times to break them up.
Don't let the king oyster mushrooms sit in the marinade too long, or they will become chewy and lose the scallop-like texture.
