Time to make the main event. We are going to roast the mushrooms, cook the spinach, then assemble and bake the parcels.
Turn your oven to bake at 200.
Remove the rosemary leaves from the stalk and finely chop.
Lay the mushrooms on a baking tray, drizzle with olive oil, sprinkle over rosemary and season with salt and pepper. Bake for 12 minutes or until fully cooked. Allow to cool.
Mince the garlic, then fry it in a large pot with a little oil for 15 seconds, add the spinach and mix well, add a pinch of salt and cook until the spinach is wilted. Strain to remove any excess liquid. Place the spinach in a bowl and mix in the cashew cream.
At this stage if you want to eat as soon as the filo comes out of the oven finish the sides in the next step now.
Get some oil or melted vegan butter and a damp towel ready.
Lay a sheet of filo on the bench and brush with oil or butter. Place another sheet on top then cut into quarters, and rotate the top sheet slightly to create a star. Lay a mushroom, or two in the center of each square, place a small teaspoon of onion jam on top then top with some of the creamed spinach, we are making about 20 of these. Gather up the outsides and scrunch them together. Repeat until all the mushrooms or filo are used up.
Lay on a tray and bake for about 10 – 12 minutes until golden.
