Add the linguine to the boiling water. Once the pasta is cooking, add the peas and zucchini to the skillet and season with salt and red pepper flakes. Toss until the zucchini begins to wilt, about 2 minutes. Ladle in 1 cup pasta water and simmer and reduce by half while the pasta cooks.
Remove the skillet from the heat, and portion into individual dishes. Drizzle with olive oil, sprinkle with cheese, and serve!
