Preheat the oven to 550 degrees Fahrenheit with your pizza stone inside.
Thinly slice the 2 green onions, discarding the upper green leafy part.
Melt 1 tablespoon of butter over medium heat in a wide pan. Add the green onions, 1 cup of cleaned and trimmed chanterelles, a generous pinch of salt (if you used salted butter, omit the extra salt), and a few cracks of fresh pepper.
Cook over high heat, stirring frequently, until tender. This should take about 2 minutes. (If you’re multiplying this recipe to make more pizzas, it will take a bit longer.)
