Preheat oven to 400 degrees F. Line a baking sheet with parchment paper and spray with cooking spray.
Make the mushroom meatballs. In a food processor, pulse together ½ lb shiitake mushrooms, ½ lb cremini mushrooms, ½ onion, 2 cloves garlic, ¼ cup parsley, and ¼ cup cilantro. Transfer the mushroom mixture to a large bowl and add ½ cup oats, ½ cup panko, 2 eggs, ½ cup grated parmesan, 1 teaspoon salt, ½ teaspoon black pepper, 2 teaspoon paprika, and 1 teaspoon cumin. Mix the ingredients until well combined. Form meatballs and place on the prepared baking sheet. Bake for 20 minutes or until the meatballs are firm.
Meanwhile, make the tomato chermoula. Heat 1 tablespoon olive oil in a saucepot over medium heat. Add 1 cup cilantro, ½ cup parsley, 1 tablespoon diced jalapeno, 1 tablespoon minced garlic, 2 teaspoon cumin, 2 teaspoon paprika, and 1 teaspoon coriander. Saute until the herbs are softened, about 1 minute, stirring frequently. Add the canned tomatoes and bring to a boil. Reduce the heat to low and simmer for 20 minutes. Season the tomato chermoula with salt and pepper.
Add the mushrooms to the chermoula and simmer for 5 minutes. Remove from heat and portion the meatballs into serving bowls. Finish with grated parmesan.
