1. **Prep the Mushrooms**: Sauté the chopped mushrooms in a skillet over medium heat until they release their moisture and start to brown (about 5-7 minutes). Let cool slightly.
2. **Mix Ingredients**: In a large bowl, combine the sautéed mushrooms, breadcrumbs, Parmesan, parsley, garlic, egg, salt, pepper, and Italian seasoning. Mix until well combined.
3. **Form Meatballs**: Shape the mixture into meatballs, about 1 inch in diameter.
4. **Cook the Meatballs**: In the same skillet, heat a bit of olive oil over medium heat. Add the meatballs in batches and cook until browned on all sides, about 8-10 minutes.
5. **Serve**: Enjoy with marinara sauce over pasta, in a sub, or on their own!
Feel free to adjust the seasonings and ingredients to suit your taste. Enjoy!
