Lightly drizzle about 1/3 cup of the melted butter over the 'shrooms and do the same with the lemon juice. Bake for about 15 minutes to soften and then set aside. Leave the oven on.
In a large mixing bowl, toss in your vegan cheese and mix with the walnuts and about 1/4 cup of the breadcrumbs. Equally divide the mixture among the mushrooms and set aside once more.
Now, with the leftover garlic, melted butter, and breadcrumbs - mix together and add the parsley. Mix again. Season with salt and pepper, taste, and adjust seasonings however you prefer. Cover the stuffed mushrooms with the breadcrumb mixture and place back in the oven for about 10 minutes. Serve hot!
