Prep the mushrooms. Cut the champignons into medium size slices and tear the oyster mushrooms into thick strips.
Sauté mushrooms. Heat olive oil in a wide pan over medium-high. Once hot, add the champignons and fry until they begin to soften, then add the oyster mushrooms and sauté until both are golden and tender.
Add protein and flavor base. Mix in the chickpeas, frozen peas, oregano, paprika, miso, spicy sauce (if using), and nutritional yeast. Stir well to coat everything in the flavors.
Add the rest of the veg. Toss in the frozen spinach and diced dried tomatoes. If using fresh spinach, hold off and add in the next step. Stir everything together for a minute.
Pour in the cream and simmer. Add the vegan cooking cream and tomato paste. Stir well to combine, and simmer for about 5 minutes, adding a splash of water or extra cream as needed to get a thick, luscious sauce. Stir occasionally to prevent sticking.
Serve hot. Add rosemary, salt and pepper to taste. Serve immediately over risotto, orzo, pasta, or rice of your choice.
