Beef with Buckwheat Noodles

Slice the onion into half-moons, cut the zucchini and bell pepper into thin matchsticks, and finely chop the garlic. Cut the beef into thin strips.

Cook the buckwheat noodles according to the package instructions.

Heat oil in a skillet and sauté the garlic for about a minute. Add the beef in small batches, sear until browned, and set aside.

In the same skillet, quickly stir-fry the onion, followed by the zucchini and bell pepper. Return everything to the pan, including the beef.

Pour in the soy sauce and add the sugar, vinegar, starch, and spices. Simmer until the sauce thickens.
