This simple and fuss-free vegan mushroom sandwich stuffs tender sauteed mushrooms, caramelized onions, and fresh veggies in a tahini sauce-slathered pita pocket, giving you a perfect plant-based lunch or healthy dinner!
In a medium pan, heat 1 tablespoon of oil over medium-high heat. Add the onions and mix them to coat with oil. Reduce the heat to medium-low, add salt, and cook for 30 minutes, occasionally mixing until golden and caramelized.
While the onions are cooking, in a large pan with a lid, heat the remaining oil, add the mushrooms, and cook until they begin to release their juices, about 5 minutes.
Add the garlic powder, paprika, salt, pepper, and the juice of half a lemon. Mix well and cook over medium-low heat until the onions are ready. Mix occasionally to make sure it’s not burning. Add a couple of splashes of water if the mixture is drying up. Continue to cook until the mushrooms have shrunk in size and are juicy and tender.
In a small bowl mix the tahini, parsley, juice of 2 lemons, salt, and pepper. Mix and slowly add water until the desired creamy and runny consistency is achieved. Set aside.
Slice the tomatoes and set them aside. Warm up the pita bread, cut it in half, and set aside.
To assemble the pita sandwiches, gently open the pita, and add some dressing all around inside. Add some spinach, one tomato slice, a scoop of mushrooms, and a spoonful of caramelized onions. Top with a little more dressing to serve.
Notes
Take your time to caramelize the onions: It can take between 30 and 45 minutes for the onions to turn golden brown. Be patient! I promise it’s worth it. Caramelized onions are rich and slightly sweet, giving this sandwich restaurant-quality flavors.
Cook the mushrooms in a single layer: The secret to tender-on-the-inside and crisp-on-the-outside mushrooms is to fry them in a single layer in the pan, leaving space in between the slices. Overlapping the mushrooms will cause them to steam instead of crisp.
Are the mushrooms drying up in the pan? Prevent them from drying up or burning by adding a couple of splashes of water to the pan as they cook.
