Prep the Protein: Toss seitan or tofu with olive oil, garlic powder, salt, and pepper. Let it sit while you channel your inner chef.
Sear It Up: Heat a skillet and cook the “thighs” until golden brown on both sides—about 5–6 minutes per side. Remove and set aside.
Sauté the Base: In the same pan, melt vegan butter. Add onions and garlic, cooking until fragrant (a.k.a. smells like heaven).
Add the Mushrooms: Toss in sliced mushrooms and cook until they release moisture and turn golden.
Build the Sauce: Pour in oat milk, soy sauce, nutritional yeast, thyme, and the cornstarch slurry. Stir until creamy and smooth.
Add Spinach: Toss in spinach leaves and let them wilt into the sauce. Drama-free, gorgeous, and green.
Combine Everything: Return the “chicken” to the pan and coat it in that creamy, garlicky goodness.
Serve & Slay: Garnish with parsley and extra pepper. Pair with rice, pasta, or your favorite carbs.
