Clean the mushrooms thoroughly. If they are large, cut them into smaller pieces.
In a large skillet or pan, heat the vegetable oil over medium heat.
Add the chopped onion and minced garlic to the pan. Sauté until the onions are translucent and fragrant.
Stir in the diced bell pepper and cook for another 3-4 minutes until softened.
Add the mushrooms to the pan. Cook, stirring occasionally, until the mushrooms are tender and have released their juices, about 5-7 minutes.
Stir in the chopped tomatoes, paprika, ground cumin, and ground coriander. Season with salt and pepper. Cook for an additional 5-10 minutes, until the tomatoes are softened and the flavors have melded together.
Garnish with fresh cilantro or parsley before serving.
Enjoy your meal!
