2. Pour about 1/4 cup of the batter into the pan.
3. Swirl the pan to evenly coat the surface with batter.
4. Cook each crepe for 2-3 minutes on each side or until golden brown.
5. Repeat the process until all the batter is used.

3. Prepare the Filling

1. In a separate pan, heat a little oil over medium heat.
2. Sauté the chopped onion and minced garlic until they become soft and fragrant.
3. Add the sliced mushrooms to the pan and cook until they are tender.
4. Season the mixture with salt and pepper to taste.

4. Assemble the Crepes

2. Sprinkle with shredded cheese if desired.
3. Fold or roll the crepes to enclose the filling.
4. Serve the crepes warm, garnished with fresh herbs if desired.
