Heat a large sauté over high heat. When the pan is hot, add half of the butter. Once the butter melts and becomes foamy, add half of the almonds and stir them around the pan for only about a minute. Add half of the zucchini. Sauté, moving around the pan, for just about a minute or two. You want the zucchini to cook but still be quite al dente. Season with ¼ teaspoon salt and a pinch of pepper. Remove to a serving dish.
Repeat this process with the remaining ingredients.
Before serving, add an extra pinch of salt (flaky sea salt, if you have it) and top with parmesan shavings.
