Bring the stock to a simmer in a small sauce pan. Set aside and keep warm over very low heat.
Heat the coconut oil over medium-high heat in a large saucepan. When hot, add the leek, garlic, 1 teaspoon salt, and lots of freshly cracked pepper. Cook until translucent–about 2-3 minutes. Add the mushrooms and cook until browned–another minute or so. Add the rice and toast, stirring constantly, until it smells nutty-about 2-3 minutes.
Add the wine, stirring continuously until the liquid is absorbed. Add one ladle of the warm stock, and stir the risotto until the rice has absorbed the liquid. Continue the process one ladle at a time until all of the stock has been absorbed, stirring often–a total of about 20 minutes.
Remove the saucepan from the heat, and stir in the Nary Dairy cheese until fully incorporated. Top with peas, add salt and pepper to taste, and serve immediately, adding a squeeze of lemon over each serving to finish the dish.
