Peel the potatoes, rinse and grate them finely (with a simple vegetable grater).
Press the grated potatoes dry in a clean kitchen towel. Tip: You do not need to have the grated potatoes pressed completely dry. It is sufficient to wring them out thoroughly and firmly once.
Mix the grated potatoes with the chickpea flour, plenty of salt, pepper, sweet paprika powder and a large pinch of freshly grated nutmeg. I mix the grated potatoes and spices thoroughly with my hands.
Heat 2 tablespoons of vegetable oil in a frying pan, add the grated potatoes in portions and press flat. Brown them on both sides for 2-3 minutes each, drip off on kitchen paper and keep warm in the oven until serving.
Peel the onion and cut into fine strips. Peel the garlic clove and dice finely. Clean the mushrooms, shorten the stems a little if necessary and cut them into slices.
Melt the margarine in a deepened pan. Gently fry the onion strips over medium heat for about 4 minutes until golden. Then add the garlic as well as the sliced mushrooms and fry for about 2-3 minutes. Deglaze the mushrooms with soy sauce and fry them for another 2-3 minutes until they are slightly tender.
Add a shot of white wine and stir in the flour.
Stir in 1 tbsp. of mustard and add the plantbased milk. Season cream sauce with salt and pepper and herbs of Provence. If necessary, add some more soy sauce. Fold in the baby spinach. I add a little bit of lemon juice for some acidity, but this is optional.
Finally, stir in 2 tbsp. of soy yoghurt and take the pan off the heat.
Wash and cut the chives. Arrange the creamed mushrooms with the crispy potato pancakes, stir in another 2 tsp. of soy yoghurt per portion and serve with plenty of fresh chives.
