My favorite vegan, gluten free version of Greek fricassée with mushrooms & spinach, that I like it even more than the regular lamb fricassée.
Sauté the chopped onions, leeks and dry onion in a saucepan with the olive oil.
Then add the sliced mushrooms and continue sautéing for 2-3 min and then add the spinach.
Add the salt, pepper, half of the dill, the lemon zest and a little water, approx. 1 cup (not too much because the vegetables will release their liquid).
Lower the heat and let it boil for 5-10 min.
When it is ready, add the remaining dill.
Separate the liquids to a new saucepan.
Prepare the sauce, by dissolving the corn flour/corn starch in 4 tbsp cold water and adding the lemon juice.
Mix it with the liquids that you have drained and put them in very low heat stirring constantly until thickened.
Serve the spinach with the mushrooms in a plate first and then overlay the sauce on the top.
