Preheat the oven to 170°C and line a baking sheet with baking paper.
To prepare the marinade, place all mushroom bacon ingredients except mushrooms in a small bowl and mix until well combined.
Clean mushrooms with a brush and remove stems. Cut mushroom tops into thin slices, about 3-4 mm.
Place mushroom slices in the marinade and gently toss to cover all mushrooms from both sides.
Transfer mushroom slices to the lined baking sheet making sure there's not too much excess marinade on the mushrooms.
Roast in the preheated oven for ten minutes then flip the mushrooms and bake for another 10-15 minutes. The mushrooms should be a bit crunchy on the edges and they will firm more after they cool. If you see mushrooms burning, lower the heat and bake for a longer time.
Wash radishes and remove the greens.
Place all ingredients in a small saucepan, stir well and bring to a boil. Cook for 2-3 more minutes over medium heat, then let cool to room temperature.
Cook your vegan burger patty as per instructions, adding two slices of vegan cheese two minutes before finishing, covering the skillet to help melt the cheese if necessary.
To assemble the burgers, cut burger buns in half. Spread a tablespoon of BBQ sauce on each half of the buns.
Place some spinach leaves on the bottom bun. Place burger patty with melted cheese on top. Add mushroom bacon, pickled radishes, and some more spinach. Top with the other half of the bun and serve immediately.
