Heat the vegetable oil in a large skillet over medium-high. Once you see it shimmer, you're ready to cook.

Toss the zucchini slices and onion chunks into the warm skillet. Let them soften up and start sizzling, about 2 minutes.
04 -
Mix in the soy sauce, teriyaki, black pepper, and chili flakes. You'll see the sauces thicken and coat everything nicely.

Keep stirring and cooking for 4-5 additional minutes. Whether you like a slight crunch or ultra-soft veggies, cook as long as you need.

Take the pan off the heat. Finish it off with sesame seeds for a nutty kick and, if you're feeling fancy, mix in butter for extra creaminess.
