Place the sesame seeds on a tray and mix to combine. Press the salmon, skin-side down, into the sesame seeds to coat.
Heat a large nonstick frying pan over medium heat. Add 1 teaspoon peanut oil and cook the salmon, skin-side down, for 3 minutes. Add the zucchini ribbons to the pan. Turn and cook the salmon and zucchini for an additional 2 minutes.
