About 8 hours before you're ready to make the stuffed mushrooms, you'll need to soak the cashews in water.
Line a baking pan with aluminum or parchment paper and preheat your oven to 375° F.
Using a soft damp cloth or a damp paper towel, clean mushrooms, removing any debris.
Remove the stems from the base of mushroom. If they don’t come out cleanly by pulling them, use a small spoon or a paring knife to carefully carve them out, being careful not to go too deeply.
Place the mushroom caps open side up on the lined baking sheet pan.
After soaking cashews, drain well.
Add them to your blender with the peeled garlic cloves and lemon juice.
As you're blending, pause and scrape down the sides. Blend until nice and smooth.
Next, sprinkle in the nutritional yeast, pepper and salt.
Add in the artichoke hearts and blend on medium speed until there are only bits of artichoke remaining.
Add the chopped sun-dried tomato pulsing a few times to further combine.
Add a spoonful of mushroom filling into each of the mushroom caps.
Bake for 20 minutes until the mushrooms are soft.
Garnish with chopped parsley and serve warm. Enjoy!
