Cut each zucchini into 2-inch sections, then split those into 6 wedges. This will make bite-sized pieces that soak up all the tasty sauces.

Heat your cooking oil in a big nonstick pan on medium-high until it glimmers. This sets the stage for your stir-fry.

Toss the zucchini and onion into your heated skillet, let them crackle and cook until they just start to soften, about 2 minutes.

Mix in the teriyaki sauce, soy sauce, chili flakes, and black pepper. Watch as it caramelizes and turns into a shiny coating for the vegetables.

Keep stirring now and then for another 4-5 minutes. Cook until the zucchini is as soft or crisp as you'd like.

Turn off the heat, sprinkle sesame seeds on top, and stir in a little butter if you're feeling it. It'll add a lovely nutty crunch and more glossy richness.
