Big, deep mushrooms are a must for this recipe. They need a good cavity to accommodate all the filling. Really, you can stuff them with any leafy green and any cheese, but, for me, the sweetness of spinach and the salty kick of Stilton complement the umami mushroom perfectly. If you feel the need for carbs, add some cooked orzo pasta to the spinach, but they are a satisfyingly complete meal without.
